Since this is a T-Mobile phone, it does use a SIM card. After a month, the phone would blackout during texting and my wife would have to start all over again with the text. Not reliable.

Yes you can. It works just like a regular phone on the t-mobile network. I returned mine though because this phone gets real hot real fast when you use it. Plus I didn't find the keyboard very receptive (hard to push buttons).

You can use a Sim card adapter. I use a T-Mobile pre pay micro Sim card and it works perfectly on this phone with the adapter.

Yes you can use your old (big) sim card. This phone uses the full size card like the older phones. They now have the full size, the mini size and the nano sized sim cards for phones. I hope this helps, Have a good day and good luck.

Yes you can, as long as the phone is on the same network as the sim card, or is unlocked, you can just switch out the sim cards and use it.

Since this phone is unlocked, you can use any GSM SIM Card in it. Moreover, I did use this phone on WiFi connection only[mine was malfunctioning and I had to return it]. You DONT need Data Connection to use this phone. Just make sure you disable Data Connection in Settings-&gt;Network Settings
