do you think prepaid carrier for iphone 4s here in the philippines esp in manila is good enough to use?
The pre-paid companies are the same ones that provide post paid services, its just the scheme that differs. Any of the networks can provide services for I Phones, however, and this is the big rub, is your I Phone open line? If you have it from an overseas carrier it is almost impossible to open line ( whatever anyone says) as it is all software controlled. Open line it and the software is affected maybe to a previous version and maybe unable to upgrade nor access a lot of services. To be fair this drawback now applies to many Smart phones. The I phone just being one of them. If you have an open lined I phone well and good ( a truly open line version is rare as they are not sold in many countries), use any local SIM. If not buy a cheap simple phone and use it while here. almost 7 years ago
