How to turn an iPhone 3GS to phone only (non-smart phone)?
I have an old iPhone 3GS that I want to use as a PHONE ONLY. Does anybody know how to do this? (I asked AT&T but they say "smart phones can't be use as regular phones" I think they just want me to pay for a data plan). The phone will be used by an elderly person that will not use the internet on the phone (therefore no need for data plan). Tried turning the data to off... (Settings>Network>Cellular Data>OFF) when inserting an old SIM card (from old "non-smart phone") AT&T will still charge for data plan automatically.
Es esta una buena pregunta?
