On some t-mobile phones you can use your cingular/at&t sims card,but on some phones after putting a t-mobile sims card in a cingular phone may cause the phone to lock up.....BUT u can unlock your phone by calling your network from another phone or logging on to your account on the internet(I PERFER CALLING YOUR NETWORK).You can also unlock it but putting another cingular sims card back in a cingluar phone then your phone should work correctly if still locked call your service provider but your t-mobile phone shouldn't get locked if u put a cingular sims card in it your phone should work perfectly fine but if not call u service provider.
tmobile usually locks their phones, so you would have to call and get it unlocked. Cingular doesn't usually lock their phones though, so the tmobile card should work in a cingular phone.
Yes if your Razr is from Cingular or unlocked. You can not use a T-Mobile Razor with Cingular prepaid sim card or Globaltravellersim prepaid international sim card unless your phone is unlocked.
You can easily add minutes to a Cingular prepaid phone. You can do so from your actual cell phone if you have a payment option connected to your account. Otherwise, you can purchase a prepaid reload card in a store and load it to the device.
yes you can, all u have to do is call the company and tell them to unlock the phone then it sould work
you cant. tmobile sim cards only work in phones with tmobile service providers. however you COULD unlock the phone.
I belive so, I used to have T Mobile and bought a prepaid phone and activated it with a monthly even more plus plan.
You usually need to get prepaid phones unlocked before they will work with a SIM from a different network.
Yes, in the case of TMobile I bought a prepaid tmobile phone and have been able to use it for my postpaid tmobile account. The sim card was smaller so I had to contact them to transfer my phone number. I know that Virgin phones can only be used with their carrier but I'm not sure what other carriers rules are.
It depends on what company you bought the phone from and if your phone has a replaceable sim card.
Yes. if it is a tmobile sim card and a tmobile phone then this will definitely work. you will also be able to carry on with the same price plan and number you used before. If you currently have a Tmobile phone on a contract plan that is complete you can also just change your plan to a pre paid plan and keep on using the phone that you have. UPDATE: As of April 2012, TMobile prepaid phones may only connect to T Mobile towers, limiting your signal (since they also use ATT towers) and giving you varied signal strength depending on your location. So, it's best to unlock any prepaid phone. Ask T Mobile to send you the unlock code or pay someone to unlock your phone.
Virgin Mobile uses CDMA, so their phones do not take SIM cards.
It will work as your existing phone.
yes it will still work.
On GSM Tracfones, if the phone has been unlocked a Cingular SIM card can be used. If the phone is a CDMA phone, no SIM cards can be used.
It depends if the cell phone is a prepaid phone with the same carrier as the card provider. If the answer is no, then my answer is no.
i have a pcs phone and i have an old cingular phone i really liked it has a sim card pcs does not can it be done
yes all you have to do is hack it my cousin did it
If your phone has a replaceable sim card, you can change the carrier. However, it depends on the current carrier if they require you to unlock the phone.
To buy your prepaid phone card, it is available at any mobile phone shops around your place.
Sim Card SwitcharooMost phones that accept a SIM card can be unlocked and used for any service that uses SIM card technology. AT&T and Tmobile phones & SIM cards can be used in this way. However Tracfone and Net10 phones and SIM cards cannot. For AT&T and Tmobile, Prepaid or Contract makes no difference. I use my ATT / Cingular contract service SIM in a T-Mobile Prepaid phone. (unlocked of course). The unlocking bit, depending on the company that makes the phone, can get a little tricky; but if you put some time into searching, you can find the information you need for a small cost or most likely free altogether. I am leaving out info pertaining to technology compatibility as most state and abroad phones are GSM, and you most likely have a GSM SIM card.
When you have a sim card most times you just pop out your sim card and put in any other phone. So I would say yes you can as long as it's not CDMA ( no sim card ) you will be fine.
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
Well, the sim card works just like any other sim card in a CINGULAR phone, but if you have the unlock codes to your other phone, I'm sure it will work.
Yes you can. . . .for example you can put a at&t prepaid go phone SIM into an at&t contract phone and it will still be prepaid.
TMobile and Verizon are incompatible. As are every other two separate phone services. The only way to use a TMobile sim card in a Verizon phone, is to get the Verizon "unlocked". You can do this at most mobile phone shops, but not all of them and most likely not an official Verizon or TMobile shop. This will cost you.
