Not sure whether this is the correct place to post this question or this should be in the iOS section. To those who have iPhones/iOS with dual sim, i just have a few questions, can’t find a concrete answer over the web: Are you able to receive calls and sms for both sim providers at the same time? Or do you have to switch sims to receive messages/calls for that sim? Verifying that only one data provider is activated at a time, so no sense in having data on both sims, with the exception of backup in case there’s no signal on the other? iMessage/facetime: only one number can be used? So you cant receive iMessage/facetime calls on the other sim? Not sure if Im not understanding something, but provider-issued iphones would have both sims locked to their network? So it’s better to buy a factory unlocked one if you intend to use Smart and Globe on the sim slots? Thanks in advance!
