Like what do you have to do to your phone in order to do that? I think you can only choose 1 sim at a time to be "working". Are you saying that you click my "home" number as the number "working" .. and the local sim would automatically be picked up because i am in the local area?newkidontheblock wrote: ↑Fri Feb 09, 2024 9:15 pmAt least the way more recent iPhones work, best I can understand.BklynBoy wrote:can someone explain how a dual sim works?

I thought the advantage of having a dual sim means you don't need a seperate phone for the country you are in abroad. BUT how does having a dual sim allow you to receive messages from your home country thru regular text?
Main number can exist as a virtual SIM or in the SIM slot. Other SIM is used for phone connection or internet. Calls or messages all go through the main SIM number.
Someone who knows more than me please feel free to better explain.
Previously had it done at the Verizon store. Multiple calls to Apple, magic behind the scenes work. About 1-3 hrs or more each time.
Now there is an add eSIM and delete eSIM under cellular. When you add a local SIM card, the phone will ask which is the primary. Calls and messages will go to the primary number.

"Calls and and messages will go to your primary number"
I don't understand what you mean by this. Any call on any (of the 2) number(s) you can answer directly, there is no forwarding. Same for messages, which can not get forwarded at all anyway.
This primary number is just the number that will be used for OUTGOING calls by default.

Re: receiving 2 factor authentication while abroad
It really depends. 2 factor using an app is generally flawless, once the app has been set up.
2 factor using SMS, or setting up an app using SMS, is indeed a Royal pain in the bum. There are several ways to spread SMS messages around the globe, but since financial institutions have most of their customers in their home market they will use the cheapest way to send SMS messages, which will generally leave out Cambodia. This means you will never receive those SMS messages sent to you. If that's the case, you have to contact the financial institution to request them to send SMS using another channel. Generally they're willing to do so if it's a one time message, but not so much if it's for a range of messages. They don't want to spend too much on you....
Re: receiving 2 factor authentication while abroad
Obv i am new to this thing because still confusing. I assumed that each sim has a phone number allocated to it. Are you saying if you put both sim cards in-- they both "work". I thought you had to select which sim card your using. I don't mean to make people crazy but ...ressl wrote: ↑Fri Feb 09, 2024 9:37 pm I am not sure, what you guys try to achive. If you have a eSiM, it is exactly the same, like you have a physical SIM. So having a eSIM + a physical SIM, is exactly the same thing, like having 2 physical SIM.
If a call gets in in either of the SIM, you can answer the call.
If you make a call, you can select, which SIM is used to make the call (there are some phones where you can preset, which numbers are supposed to use which SIM).
Both SIM are active (5 years ago only one SIM was active, but all phones are capable of that now).
To go back to 2FA - if you don't get the SMS on a single SIM setup, eSIM or dual SIM or whatever doesn't solve the issue at all
because the 2 factor authorization is going to my "home" sim card number. If i understand correctly, using the "local" sim card helps this? //fuck now i am even frustrated

Re: receiving 2 factor authentication while abroad
Having 2 SIMs in one phone is basically just like having 2 phones in one. Both SIM are operating independently from each other, when it comes to incoming messages. If a SMS is sent to SIM (number) A, but A has not network, only B has, then you won't get the message.
For calls you can set up a forwarding (gets billed the same way, like you would do a call to this number you are forwarding, so careful with international forwarding numbers), but there is no way to forward SMS

Re: receiving 2 factor authentication while abroad
thank you!!!! now that makes sense and i understand.. MUCH APPRECIATED. So having a local sim (B) doesn't help at all when expecting a text to Home SIM (A)ressl wrote: ↑Fri Feb 09, 2024 10:12 pm Having 2 SIMs in one phone is basically just like having 2 phones in one.

The point of a dual sim is like you said..2 phones in one. but they operate independently.. For some reason I thought having dual sim would somehow help to get home texts when abroad. All it does is basically save you money so no need to get an extra phone when abroad

Re: receiving 2 factor authentication while abroad
I have a dual SIM phone and (depending where you are!) it is not a one or the other deal. Both work at the same time although you may need to go into settings and choose which one you want as default for calls and data. I am not currently there but a month back I was using Smart and my Telcel at the same time and while I had both calls and data set for smart my Telcel worked fine when I needed a SMS for 2 step auth.
Re: receiving 2 factor authentication while abroad
Sorry to keep on about this but wanted to confirm something. If I understand correctly, If i get a text from my home country, the text can come thru via the local sim and use the money/data from the local sim?ressl wrote: ↑Fri Feb 09, 2024 10:12 pm Having 2 SIMs in one phone is basically just like having 2 phones in one.

is the above correct?

Re: receiving 2 factor authentication while abroad
Hi,
I've been reading the forum for entertainment since my visit a couple of years ago, I can help with this.
I'm in Hong Kong and facing the same issue, ie need to be running on a local sim but also need to receive texts for 2FA when doing certain transactions.
Dual SIM is the way to go as mentioned.
You have your own country SIM set to roaming so it can pick up texts but you set the mobile data to your local SIM. For me being on the O2 network in the UK, the texts I get are free (but obviously you need to check this) . Obviously I don't want to receive or make calls on my UK SIM, or send texts, as that costs money, but receiving is fine.
Re: receiving 2 factor authentication while abroad
So for example, when I'm HK and I buy a UK train ticket online in advance to get me home from the airport in a couple of months, I do it on the phone using the local Internet or WiFi.
The UK visa debit transaction will send a verification text to my UK number which happens to already be in the same phone and is free to receive.
