IPhone AT&T, T Mobile sim switch issue?
I have a iPhone 3GS I'm trying to do the T Mobile SIM card switch to get the MMS working. I bought the sim brand new on Ebay. When I insert the sim my phone displays "sim failure". Any suggestions? Does the sim need to be activated?
A SIM will do nothing… If it is not activated to some mobile phone carrier. Maybe you should call t-mobile if that is the mobile provide you want to use (and pay them).
a sim failure is not good, did you put the sim in backwards?

- Reuse T-Mobile cut-to-use-for iPhone SIM card back to regular T-Mobile phone? Is that possible? My SIM card has been cut to fit on iPhone but I'm going to sell it next month to go back to regular T-Mobile phone. I still have the cutout piece from original T-Mobile SIM Card. Can I re-attach micro SIM to original T-Mobile card and use it on new T-Mobile phone, or would I have to buy the new SIM card and activate it again on pay-as-go-plan?
- How to fix service/signal issue on iPhone 4 T-Mobile? Hey guys I have an iPhone 4 and I have T-Mobile. I can never get service in certain parts of the building where my friends that have AT&T can. Could anyone guide me to a tutorial on how to strengthen my signal? I'm currently running iOS 6 and am jailbroken so if you have an Cydia tweak that helps let me know.
- Dual SIM adapter issue - iPhone 5? The dual adapter works fine when I have a payg Orange and a payg T-Mobile SIM in place, but whenever I remove either SIM and insert my contract EE SIM, the phone displays 'invalid SIM'. My EE SIM works when used in the phone without the adapter. I'm obviously wanting to use my contract EE SIM in conjunction with any of the 2 payg SIMS. Any ideas are greatly appreciated.
