you have to go online to buy a unlock code for the phone, once you have the unlock code you can put the sim card in and it will ask you for the code.
if not you can buy a sim card holder that can convert your tmobile sim card into the at&t phone so you have use of the at&t phone, but with tmobile!
get it?
yes, you can. as long as your sim card will fit in the sim card slot.
oyu can use any unlocked att phone with a sim card port
Yes, but it has to be a phone that can accept the sim card, and it must be unlocked by the previous company. ex. if you have a tmobile phone you want to use, call tmobile and have it unlocked, then put your att sim in. It is not recommended though due to data services will generally not work. p.s. Iphones can not be unlocked by anyone.
You can put any SIM card in an unlocked cell phone.
If you mean putting an at&t sim card in a t-mobile phone, no. Sim cards only work in phones that are the same brand.
No, I've tried. You have to insert a special code. (3 tries and the phone locks down) You have to get another att phone.
No most phone companies do not allow any SIM card to go into all phones. The only exception I have found is the SIM cards for ATT phones and TMobile phones.
Yes as long as the phone is att and has a sim card slot
Yes, provided your ATT phone is SIM unlocked.
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
yes you can but only in an att phone.
If the T-Mobile phone is unlocked meaning the network unlock code has been given to the phone. Contact T-Mobile for the Unlock code after you have an active AT&T account and sim card.
Yes, just switch the sim card.
yes it will still work.
The sim card will only work in a different phone if the phone is ulocked, in not, no
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.
Yes you can! as long as the phone is unlocked any sim card will work in it :)
yes but the phones has to be unlocked.
yes u can I had my att go phone unlocked and tried to use my sim card from st. talk which I found out uses att service towers in my area however, it didn't work. It stated "sim crash"
Unfortunately no.
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
no it does not . it fits into a blackberry 8350I from nextel but it doesnt fit into any tmobile or att.
you cant. tmobile sim cards only work in phones with tmobile service providers. however you COULD unlock the phone.
No you cannot. CDMA phones do not accept SIM cards.
