If you’ve been the victim of a prank call from a cell phone at 2 o’clock in the morning, you might be tempted to do a reverse cellphone number lookup to find out information about the culprit. If you thought it would be free however, you’ll be disappointed to hear that you cannot perform it for free (sorry to burst your bubble!). Most sites that can perform a reverse cellphone number lookup will charge you in some ways or another.

There are no directories for cellular numbers as there are for landline numbers that allow you to trace a number for free yet. Companies that offer this service have to gather their information in ways that cost them money, and that’s why the best way to obtain legit information on a cell phone number is to pay for it.

Paying for a reverse cellphone number lookup

A single trace will cost you around $15 from most lookup web sites. If you use the feature often, some sites allow you to subscribe to a special plan giving you an unlimited number of traces for a period of time. Paying for a reverse cellphone number lookup is the most accurate way to obtain all the information you want, but make sure to do it from a site you trust. Many sites in this industry seem a bit suspicious (especially those offering free reverse cellphone number lookups – see below).

Free reverse cellphone number lookups – oh really?

Some websites claim to give you free number traces. You have to be careful around those sites though, because most have ulterior motives. While researching this article, I found one that would trade you information about a number for your personal information and offer it to marketers and other third parties. If you do want to try it though, make sure to read the fine prints of the end user license agreement when you enter any personal data.

Basic cell phone number information IS free

Some information is better than no information at all. While you can’t do a full reverse cellphone number lookup for free, you can still obtain basic information on a number by using a free directory such as 411.com. This directory will give you information such as the country, state and city the cellular phone number is from.

Google is your friend

There is an alternative to all the sites that can trace numbers, and it’s our friend Google. Simply type the number you want information about in the search box, and if you are lucky you just might find a web page with all the information you are looking for. Maybe you’ll find the number that has been calling you a 2 o’clock in the morning on the user’s Facebook page.

You have to be very careful around sites that claim to do a reverse cellphone number lookup for free. More often than not, these sites have ulterior motives such as gathering personal data, or the information they provide is pretty basic. If you can’t gather enough information from Google, the best way to do a reverse cellphone number lookup is to pay for it from a site you can trust. Have you ever used a site to do a reverse cellphone number lookup? Which one was it and how did it go?

3. Protect your cell phone with Save

Verizon Wireless wrote a press release to offer cell phone tips to prepare for unpredictable summer weather, most of which I found pretty basic but still interesting nonetheless.

• Keep wireless phone batteries fully charged.

The last thing you want during an emergency is to run out of battery.

• Have additional charged batteries and car-chargers available for back-up.

That way your cell phone will work until you run out of gas :) You can buy spare cell phone batteries and cheap chargers here.

• Keep spare wireless phone batteries, chargers and other equipment in a dry, accessible location.

Failing this, maybe you can still save your wet cell phone.

• Maintain a list of emergency phone numbers — police, fire and rescue agencies; power companies; insurance providers; family, friends and co-workers — and program them into your phone.

That is actually a very useful tip. Most of us tend to keep only our friends and family numbers programmed into our phones, but you can store business and emergency phone numbers there too.

• Distribute wireless phone numbers to family members and friends.

Pretty obvious, and make sure you have theirs too.

• Forward your home phone calls to your wireless number if you will be away from home or are forced to evacuate.

And answer selectively using caller ID. You still don’t want to be bothered by work if you’re on a getaway trip.

Thanks Verizon!

Many cell phones allow you to set an alarm or a reminder at a certain time or date. Even if you don’t own one of the latest smart phones that come with killer time management applications, it is possible to use your cell phone as a time management tool (even if it’s 5 years old like mine). The following cell phone tips are usable on just about any cell phone – the only features it needs to support are alarms and reminders.

You could use your cell phone alarms and reminders to:

• Remember birthdays

My cell phone is recent enough to come with a basic calendar, which I use as a reminder of my friends birthdays. I’ve always been horrible with dates, so I even setup an alarm to warn me one day before the birthday. I set the event to be recurrent every year, so I don’t have to bother setting it up again for the next year.

• Make sure you don’t miss an important deadline

You know the kind: “How am I going to remember that!” you tell yourself. And before you realize it, you missed it. If you have an appointment or deadline you are predisposed to miss, set up an alarm to remind you of your appointment a few hours before it happens.

• Take a medication

Remembering to take a medication every day can be a real pain, especially if you are somewhat active – never home at the same time at night and sometimes sleeping all morning, it’s easy to forget. Simply set up an alarm on your cell phone to remind you to take it (especially handy when you carry your medication on you).

• Know when you’re available

You’re receiving social invitations left and right and can’t seem to figure out when you’re available? Simply mark all your events in the calendar on your cell phone. You’ll see right away if you’re available when someone invites you to an event.

• Organize your day

Respect your time budget throughout the day by setting alarms on your cell phone to warn you of different time periods. Never miss a break period again!

• Alarm clocks anywhere

Whether you’re traveling alone and dozing off at the airport, are afraid the (sometimes complicated) hotel room alarm clock doesn’t fire off, or are having a lunch nap at work, your cell phone alarm clock is often overlooked and can be used just as that – an alarm clock.

Have you found any innovative ways to use your cell phone alarms and reminders? Share your cell phone tips with us in the comments below!

Using a sugar cube, Instructables shows us how to remove unwanted logos from a cell phone. The idea behind it is to use a sugar cube to scratch off the stickers on the cell phone. The sugar should not leave a mark on plastic or metal. Process with the following steps at your own risk – in the worst case, you could damage or leave a scratch on your phone.

1. Place tape around the area you’re going to scratch. This is important because you don’t want sugar to get in the phone.
2. Scratch the sticker with a sugar cube until it has disappeared completely. Repeat until the cell phone looks clean.
3. Remove the tape and clean up the remaining sugar with a dry cloth.

If all went well, you will have a clean unbranded cell phone, with those pesky stickers from your carrier gone forever. Apparently, this trick will not work on some cell phone covers though – the sugar cube will leave a mark.

While most cellular phones now support all three types of ringtones, it is good to know the difference between monophonic, polyphonic and true tone ringtones before spending bandwidth (or worst, money) on a ringtone version of the latest James Bond theme.

Monophonic ringtones

In the early days of cellular technology, most cell phones were only able to emit basic tones on different frequencies. The monophonic ringtone uses basic sequencing technology to play a song: it’s a one instrument, one note at a time thing. Monophonic ringtones are a good choice if you are looking for a clear, easy to discern ringtone for your cellular phone. Most monophonic ringtones are available for free or for very little money because they have since been outclassed by the more popular polyphonic and true tone ringtones.

Polyphonic ringtones

Like the monophonic ringtone, the polyphonic ringtone employs sequencing technology but to a much higher level. Instead of playing only one note at a time, up to 40 notes can play at the same time. Polyphonic ringtones can also emulate different musical instruments, simulating a digital orchestra in your pocket when your phone rings. Polyphonic ringtones lack one thing: the ability to use digitalized audio samples.

True tone (or real tone) ringtones

True tone ringtones, also called real tone or full music ringtones, can play actual music. Addressing the issue of instrument samples limitation, the true tone ringtone can play fully digitalized audio samples such as MP3s, including the vocals. While true tone ringtones can be highly personalized, they are often quieter and harder to discern in a busy environment so they might not be the best choice for someone who works in a shopping center. True tone ringtones gave birth to the most annoying ringtone ever created, the Crazy Frog ringtone.

The ringtone business is currently flourishing: worldwide, it’s a $4 billion market. With over 50% of all US cell phone users having downloaded a ringtone at least once, ringtones are also a great marketing tool for audio products. Do not be fooled by the possiblities a true tone ringtone offers you though: nothing will ever replace the stunning clarity of a monophonic ringtone!

3. CDMA vs. GSM, Which One Is the Best for You?

Are you looking to pick a side between CDMA vs GSM, the two major telecommunication standards that are used by the cellular networks worldwide?

It can be a hard choice to choose between CDMA vs. GSM, as both have their own advantages. When in the hunt for a cell phone carrier, you may have to figure out which of these two technologies is the best for you and hopefully this article will shed some light on the whole CDMA vs. GSM issue.

CDMA vs. GSM: Breakdown of the technologies

The Origins of CDMA and GSM

CDMA: Code Division Multiple Access is a technology developed by Qualcomm in the United States, and it is currently the dominant network standard in North America.

GSM: Global System for Mobile communications was invented in 1987 by the GSM Association, an international organization dedicated to developing this standard worldwide.

CDMA was established earlier in North America and thus has a bit more coverage than GSM. GSM on the other hand is an international standard backed by an international organization and the protocol is a more mature and thus more robust. There is no clear winner in the CDMA vs. GSM debate here; it all depends on your needs.

Coverage of CDMA vs. GSM

CDMA: It is mostly used in America and some parts of Asia. It is currently making progress in other parts of the world, but the coverage is still limited compared to the GSM technology. Its support is currently non-existent in Europe because the European Union mandates the sole use of GSM. In North America however, CDMA generally offers a better coverage than GSM in some rural areas because it was deployed earlier. Its network reaches over 270 million users worldwide.

GSM: Being an international standard, it is better suited for international roaming, provided you own a quad-band cell phone (850/900/1800/1900 MHz). The GSM network is also well established in North America, but not as much as the CDMA network yet. Its network reaches over a billion users worldwide.

CDMA is prominent in North America, but GSM reaches a lot more users worldwide (about 1 billion vs 270 million). In the CDMA vs. GSM debate, GSM wins if you plan to travel to foreign countries but CDMA might have a better coverage in your area.

Data transfer

CDMA: The best data transfer technology it has to offer is the EVDO technology, allowing for a maximum download speed of about 2mb/s (about 700kbps in practice), which is similar to what a DSL line has to offer. EVDO is not available everywhere yet and requires a cell phone that is EVDO ready.

GSM: Offers EDGE, allowing for a maximum download speed of 384kbps (around 140kbps in practice). More technologies are being developed on top of EDGE such as HSDPA to boost the transfer rate to over 384kbps in practice. This technology requires an EDGE-ready cell phone.

CDMA offers faster data download and would therefore be the favoured choice for data transfer. GSM is catching up fast however, but its EDGE technology is subject to interferences.

Phone Identification (SIM cards)

CDMA: Your account information is programmed into your cellular phone. If you want to change your phone, you have to contact your carrier and have them reprogram your new phone. You will also need to re-enter your contact list and calendar information into your new phone. If you have a lot of contacts, your carrier might be able to help you perform this task. Some CDMA2000 cell phones support R-UIM cards (Removable User Identity Module) which are used to store account information and contact lists, but these are not very common in North America yet.

GSM: Your account information along with your contact list and other personal data are stored on a SIM card (Subscriber Identity Module). It is a small chip you can freely remove from your phone. When you get a new mobile device, you can simply insert your SIM card into it and it will work with your current account information and contact list. If you travel to another country, it might even be possible to purchase a prepaid SIM card which you can use to avoid roaming fees.

GSM is a clear winner here. The SIM card technology offers many advantages if you plan to travel or switch phone often.  CDMA phones are slowly catching up with R-UIM cards, but cell phones that make use of this technology as still rare.

Which technology is the best for me?

When asking yourself which technology to choose between CDMA vs. GSM, first ask yourself the following questions:

1. Is international roaming important to me? If you travel a lot to foreign countries, you might want to opt for a GSM phone for a better coverage.

2. Am I going to transfer a lot of data using the phone? If you intend to use the phone for mobile web browsing, watching television or downloading MP3s, you might be better off with a CDMA phone. Currently, it offers the best data transfer speed with its EVDO technology and is the clear winner for now.

3. Do I plan to change phone often? If you do, a GSM phone is best for you since you can swap the SIM card to a new device without having to re-enter your personal data.

Once you have established your basic needs, compare CDMA and GSM signals in your region. Also compare the carriers offering both services in your area. Talk to your friends and colleagues and ask them if they are satisfied with their cell phone carrier and how good their signal is. Remember, when choosing between CDMA vs. GSM, preferring a network technology over another also means limiting your choice in carriers.

One day at the pool, the inevitable happens: you get thrown into the water by a bunch of your drunken buddies. In any case, the $300 cell phone that was in your pocket got wet. Unless you own a water proof cell phone, you’ll want to know exactly how to dry out a wet cell phone, because you might still be able to repair it.

1. Remove the battery. This is the most important part! Damage in wet electronic devices mostly comes from short circuits. Removing the battery quickly will prevent electricity from further damaging the phone. Resist the temptation to test the phone while it is still wet!

2. Remove the SIM card (if applicable). The SIM card should have survived, but make sure you don’t use it again until it has dried completely.

3. Disassemble the phone. Use the required screwdrivers to disassemble the phone as much as you can. Note that disassembling the phone will probably void your warranty, but then so will dropping the phone in water. You’ve got nothing to lose. The reason for the disassembly is simple: the phone will dry up much faster once it is disassembled. You could skip this step, but water can remain inside the phone for weeks if you don’t do it.

4. Dry the phone as much as possible using q-tips or paper towels or a similar material. This will prevent water from getting further into the phone. Two ideas to help with the drying:

• Heat the phone. Heat will help water evaporate. Leaving the phone under a desk lamp for 24 or 48 hours might help. WARNING: Do not overheat! Just a little warmth is enough. Heating the phone too much can further increase the damage done to it.

• Use a fan. Leave the phone under a desk fan for 24 or 48 hours.

5. Test the phone. After a few days (usually two or three), the phone should be clean and dry. Reassemble the phone and put the SIM card and battery pack back in. If it doesn’t work, there is a chance your battery has died from water damage. Try an alternative power source. You can get another battery for cheap if your phone still works.

As always, be very careful when disassembling electronic devices. Know you warranties and insurances well before attempting anything, and make sure you note how to reassemble the phone. Repair a wet cell phone at your own risks.

Hopefully, you will manage to save your wet cell phone from drowning!

Today I received a brand new credit card because my old one had expired. To activate the new card, I had to call my credit card company so they could verify the card was indeed in the hands of the rightful owner. Having dropped my land-based phone line recently, I made the call from my cellular phone, and I had to type in my credit card number on my cell phone keypad. After the call I had the idea to check if my card number could be found anywhere on my cell phone – it was indeed very easy to find.

It is important to realize how sensitive information on a mobile device can be. If your mobile phone is stolen, such information can be leaked and at worst lead to identity theft. There are basic cell phone tips you can follow to help prevent it from happening:

1. Beware of your phone’s history of dialed numbers. On all cell phones you have access to the list of recently dialed numbers and received calls. These numbers may contain information you typed on the keypad of your phone – information such as credit card numbers. It is important to clean up such information after making a private call. Keep in mind that not all cell phones record information at the same place. My RAZR V3c from Bell Mobility has a Notepad feature which records the key I press during a call. This feature can be a danger to your privacy.
2. Keep contact list information simple. Do you really need to keep your family member’s addresses on your cell phone? If your cell phone is stolen, the thief will not only most likely learn who you are, but he will also learn who your family member’s are and where they live. Keeping your contact list simple and stripped of important information will definitively help protect your privacy.
3. Remove important information from your agenda. Most cell phones have a calendar feature which can also act as an electronic agenda. If you keep your appointments in there, a potential stalker will know about your next appointment if he can have a look at your phone. I’m not saying to forget the feature, but you might want to keep the information basic if you’re concerned about your privacy.
4. Erase sensitive text messages. If you are using special text message services like Paypal Mobile or even MSN Mobile, make sure you delete the history of sent and received messages containing information such as passwords or personal information.
5. Disable the GPS feature. Some cell phones have a GPS tracking feature, allowing for example automatic time change when you travel between timezones. This might be a little far fetched, but if you are concerned about someone tracking you, you may want to turn off that feature. However, keep in mind that the GPS tracking feature can be important in the case of an emergency, as it allows 911 services to track you easier.
6. Put a password on the cell phone. Adding a password to your cell phone and locking it can help prevent information thieves from accessing your information. It will not stop a dedicated person from cracking the password, but it certainly will slow him down.
7. Make sure you erase all personal information before you give the phone away. If you want to give your cell phone away for recycling or sell it to another person, make sure you erase all information from the phone. Most cell phones have an option to erase all information and reset to factory default buried deep into their menu system.

Cell phone privacy is something we should all be concerned about. While these tips are aimed at cellular phones, they can also be applied to other mobile devices as well. If you’re concerned about your cell phone’s privacy, take steps to help protect yourself. Better be safe than sorry!
