Greetings,
Will an unlocked AT&T iPhone 4s with a T-Mobile SIM (that has NOT been activated) display the true data connection speed in the phone's display?
I want to leave AT&T for T-Mobile, and port my mobile number and unlocked iPhone 4s. But I live in Des Moines, Iowa and I am concerned about T-Mobile data speeds on the iPhone 4s.
Recently T-Mobile offered a promotion for two free micro-SIM cards. The unactivated SIMs arrived today so I loaded one and my iPhone 4s is showing "T-Mobile 4G". Will an unactivated SIM report the true network/data speed? Or is that the default display until the SIM is activated? I can't transfer service until I know that the speeds in Des Moines on T-Mobile with an iPhone 4s will be better than 2G.
Thanks in advance,
js
