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!
Mm... https://support.apple.com/en-au/HT209044 As for keeping both lines data-ready, yes, for times when Globe LTE is weak, you can readily switch to Smart and vice-versa. And yes, locked eSIM as well for telco-supplied iPhones. Best recourse is to just get the nano/nano sim factory unlocked units from Apple HK (the Xs Max and Xr) or HK phones being sold in Greenhills or if you fancy factory unlocked eSIM/nano sim for Xs Max, Xr or Xs, get it from Apple PH or authorized resellers here or Greenhills ( most likely the Singapore iPhones).
Thanks for the info! Appreciate it. I actually saw this already, but i wasnt sure how it would work in our (ph) context, not sure we have voicemail (i havent tried/checked). I know call forwarding might work but im not sure it would work for inter-provider..have no real experience on it. Also the article isnt really clear about receiving messages, whether i have to switch to receive messages from the other sim. With regards to both sims being locked to the same provider. This i could not believe, that’s why i asked for verification.
Mm...no voicemail. Stupid duopoly left out that network feature. Call forwarding in the PH has been around as far as I can remember.....Nokia days? It works like this: when you receive an SMS from your secondary line, you will receive it real time. Reply as usual. Your reply will be sent through your secondary line. Same thing with your primary line. Messages received from your primary line and replies will be sent through your primary line. However, if your reply fails to get through (weak signal) from either your primary or secondary line, the iPhone will allow you to either cancel, try again or reply using the other line. The problem is the iPhone does not allow you to choose which line to use (primary or secondary) once a conversation thread is started. Once a conversation thread is started using your primary line, the iPhone will always use the primary line. Same thing with the secondary line. Except when there is a message failure or if you are initiating a message from a number that is not in your contact list. The workaround: if your contact has multiple contact numbers, do not merge your contact’s numbers under one entry. Example: Jose Globe number, Jose Smart number. That way, you can maintain separate message threads and choose the line you want to use for SMS. This only works if you do not have an existing messaging thread with a contact. Complicated. For calls, it is far simpler. You can use either line to initiate a call to your contact, if you so choose or designate the primary line to always initiate calls or designate the secondary line to always initiate calls or let the iPhone use Last used (line) for that specific contact. Me? I just let the iPhone do its thing and manage the calls or SMS, regardless of where it is coming from. Uncomplicate it instead of micromanaging it. The important thing is you will receive all your messages or calls in real time from your primary or secondary line. No need to switch. For mobile data switching, simple: just click the network that you want to be active. Switching takes around 10 to 15 seconds. That’s it.
My uncomplicated life means ONE line on a duo-sim iPhone...besides I can call whatever line I can on this ONE line... To have another line to the XsMax is chaos...
Thanks for the info! It’s nice to know that you still receive messages real time! I was worried about this. Yeah it might be a good idea to have separate entries for different providers. Yeah, that’s when i tried call forwarding, havent tried it since then, i just assumed it’s still around. So you cant receive calls realtime like in messages? Mmmm...Might be a deal breaker.
Mm...the workaround is actually not recommended. Why? Because the first thing that we do when we buy a new iPhone is to migrate our data from our iCloud backup. And that includes all our existing messaging threads. It is just too much work. Unless you prefer to start with a blank slate. In that case, go knock yourself out and enjoy designating which of your lines gets used for which contact........with a thousand names in your contact list? Good luck with that. Again, to clarify, all calls (because of call waiting) and messages will be received in real time, for as long as both your lines have signal from their resepctive networks, because both lines are active at the same time. As for incoming calls while you are in call mode, it works the same as before. Call waiting is still working for dual sim iPhones. For call forwarding, go to: Settings - Phone - Call Forwarding - Globe and Smart (or whatever label you used to name your phone lines). Just toggle the switch to enable call forwarding on either line. A small icon will appear at the top of your iPhone display to indicate call forwarding. Useful now that iPhones have dual sim.
Didnt really thought of that! I probably am trying to justify that dual sim would work. No idea how they are inplemented by other phone manufacturers, so im clueless, really. Haha! Thanks for the replies. Really appreciate it.
Sorry, missed the part in your reply that you can still receive both sms and calls realtime without having to switch! That’s great!
Mm...yeah, there is a steep learning curve for us iPhone users because this is the first time Apple has implemented dual sim.
