put it in the top slot or buy another sim card
It depends on what company you bought the phone from and if your phone has a replaceable sim card.
When you buy a tmobile phone it camoes with a sim card. If you already have a tmobile phone and break it you can buy a pre-paid phone and put your old sim card in it
If you have used TMobile in the past, you can unlock your HTC Touch Pro2 by calling Tmobile. Alternatively, you can purchase unlocking software on websites such as eBay which will allow the unlocked phone to work with an AT&T sim card.
no you cant put tmobile sim card into a at&t phone- since it is a different company and provider the sims cards are toatlly different
You can put any SIM card in an unlocked cell phone.
if the tmobile phone uses a sim card then no, if it doesnt then probably. if the phone is locked you will have to call tmobile or lg for the unock codes
No. Each carrier has allowed cell phones for their carrier. If you have a GSM carrier though, you can buy an unlocked phone to use on that carrier even if the carrier doesn't support the phone. All you do is move your sim card.
Yes you can. You can put any tmobile sim card into any tmobile or unlocked phone and it will work perfectly. Although you may need to add some features to your plan :)
You can - but - it will only work if the t-mobile phone has been unlocked !
You can not use a sim card in another cell phone carriers phone. They can only be used for the same carrier.
Some cell phones are designed to use a Subscriber Identification Module (SIM) card, or microchip that stores subscriber data. The SIM card is issued by a carrier and provides cell service by activating any phone into which it is inserted. A locked phone, however, will only recognize a SIM card from a particular carrier. If the cell phone is unlocked, it will recognize a SIM card from any carrier. The "lock" is a software setting that keeps the cell phone "loyal" to one carrier.
It could just be that the SIM card has gone bad, They can be changed out easily by your carrier.
