Questions about GSM Phones

GSM stands for Global System for Mobile communications and is a cell phone technology that is widely used all over the world. In the U.S., T-mobile and AT&T are two big mobile carriers that use phones that operate on GSM. Among its many advantages, GSM phones use a SIM (Subscriber Identity Module) card that helps to identify the user and allows them to switch phones while staying connected to the same network. GSM carriers also have deeper penetration in rural areas through roaming contracts with other GSM carriers, providing users the opportunity to travel anywhere and still stay connected. Listed below are a few questions about GSM phones that have been answered by the Experts.

What is the way in which a Motorola i1 from Boost Mobile can use a GSM card and network?

This is not going to be easy to do since the only way to turn a CDMA or an iDEN phone into a GSM phone would be to take the phone apart and install new hardware, firmware and software. It may be easier to buy a GSM i1 instead.

Is there a way to fix a Nokia N95 GSM, the dial pad isn’t working after changing the housing on it?

It’s likely that the problem stems from the new casing not being fitted properly. In this case, just remove the casing and reinstall it. This should work and sort the problem out.

The keypad on a Motorola V550 GSM mobile phone lights up but not the screen this happens even after removing and replacing the SIM, what can be done to fix this?

To fix this, first try and remove both the battery and the SIM card. After twenty seconds, connect the phone to the wall charger, put the battery and SIM card back in and switch on the phone. This should help sort things out. In some cases, the phone may need to be charged overnight to fix the problem.

Why would a Motorola V3 GSM cell phone flash a message that says "unable to charge"?

This problem is commonly seen on the Motorola Razr and E815 series. It isn’t a battery issue and the actual fault lies with the charging module. In this scenario, the entire charging port may need to be changed to sort the problem out. This is going to be expensive and may even work out to more than the price of the phone. It may be a better idea to get a new phone instead.

Can a Motorola 280i GSM phone be internally adjusted in order to use the 850M hz band?

This may not be possible as the hardware is not designed to use an 850M hz band. As a result, there will be only certain frequencies that the phone can work on. GSM phones are widely used by people all over the world and have many advantages. However, as is the case with any technology, it can be frustrating when things go wrong. While a few issues related to GSM phones are discussed above, there could be others that are specific to each case. Direct these to Cell Phone Technicians now who can offer professional insights and opinions both quickly and affordably.
