How Dual SIM on the iPhone Works

Want to add a second line to your iPhone? I decided to try it and I love how it works. Now you can receive calls, text messages, and use data from two different lines on your iPhone.

I have used a dual SIM iPhone for two years and have loved it! I am seamlessly able to switch between my Work and Personal phone lines. Even though my Work line is through AT&T, and my Personal line is through Verizon, the iPhone has been able to handle phone call and text messages from both lines. It has worked great!

I’m looking to start a business and do a phone upgrade. Saw that the SE 2020 had dual SIM. When I researched whether or not the 12 also had dual SIM, I came across this video. I’m glad I did 👍🏽 Thank you! This was more information than what I was looking for, but it was very helpful

[@JSantana319]

I think Apple’s implementation of the dual sim is the best I’ve experienced. I have an iPhone XR and a OnePlus 7 Pro with dual physical sim. I prefer the way the iPhone works through the eSIM due to the cellular switching while on a call. You don’t get that option with the OnePlus, you do get a toggle to switch data cards, but not while I’m on a call. With the OnePlus you don’t get voice and data if you’re calling from the SIM card that’s set to calls and texts, which is a bummer. I hope more oems take notes from Apple and implement this to their devices. Awesome video!!

[@alloshow]

Thank you Thank you. The Apple care lady told me you couldn’t put two different messages on the phone. Thank again

[@mikkel4372]

Does text messages also have the P or B label so it’s easier to separate private and business messages?

[@projectpete19]

Can you receive calls from either line at any time? Meaning if my personal line is my primary, is my secondary eSIM number always listening and the phone will ring if someone calls it?

[@rekardosmith4436]

So when you said you can group your contacts is there anyway that you could have two separate message threads??? Like I would prefer if my text message screen gave me the option to just see “business” or “personal” line messages. Then I’m not getting business texts buried by personal texts that come in much more often. Great video 👍🏻

[@MrNick-]

Well said ... I wish Instead of selecting Primary and Business all the time, I wish they made it so you can switch from Primary main screen, or Business main screen.

[@cystarkman]

one huge benefit in my mind with the esim is added security. i have esim only. this means if someone steals my phone they cannot prevent network access by ejecting the sim. also when i travel os i can drop in a 2nd sim easily without risk of losing the other sim or losing whatever os connection options my home carrier offers.

I ordered the iPhone se 2nd gen and will receive it next week, glad I read this now when I get it I'll be making my esim my main number with telstra and the nano sim can be optus for other purposes Do you think itd be better to have two carriers or just the one? And if both sims are with one carrier can I choose what my prepaid service works on the sims? So I don't have to pay two services?

[@jeffflowers729]

After seeing all the settings and setup needed and the issues in all the comments to run dual sims, I'll just keep my Sideline app. For $70 a year I have a fully integrated second line that functions exactly as the native phone app piggy backing on my carriers plan. You can take calls from lock screen. Tells you it's a Sideline call coming in and you can have a different ring tone to alert you it's a business call. The exception is that calls and text and voicemail are on the one app, which is actually great for my business use because all my interaction with that client is organized in one thread.

[@Devin_Schwartz]

@Jeff Flowers - Do you still use Sideline? It looks like all of the more recent reviews are quite putrid.

[@jeffflowers729]

@@Devin_Schwartz I do. It’s been my business line for many years now. I really like that calls and text are in one app so I can keep track of my contacts with clients. Recently they have had some outages and hiccups and it can be frustrating , all carriers can, but they fix it. It’s still a bargain over adding another att e sim line on my iPhone.

[@clarkmaurer]

When a call comes in, how do you know if it's a business call or a personal call? Maybe the call has a label for Business or Personal on the screen? I'm just guessing. Also, can you configure different rings for each sim?

[@HandballMr]

I know it’s a hassle, but you can of course assign different ringtones to different contacts. Now if you two groups of contacts (private / business), maybe you can even assign ring tones to the whole contact group? That would be a nice workaround....

[@apersontrappedinabody9025]

Set a default ringtone for all calls and for your personal contacts, choose a special ringtone for that. I know it’s not gonna solve your problem directly but I think it can mitigate the problem.

Today I dumped T-Mobile’s Digits App that I had been using as my secondary business line but it was so janky that I tossed it.

Instead of selecting Primary and Business all the time, I wish they made it so you can switch from Primary main screen, or Business main screen. If you’re on the Primary main screen, everything you do is from Primary. If you were on the Business main screen, then everything you do is on the Business number

[@tomburke5311]

I use this facility on my iPhone XS when I'm travelling in Asia. Roaming costs in Asia on a UK network (I live in the UK) are very high, as are call & SMS costs - they won't be included in your allowance. I used to just get a local SIM (e.g. in Singapore or Dubai), take out my UK SIM, and then get messages to my family, etc, giving them my new, local number. With the new system I'm got my regular UK line set up with the e-sim so when I'm travelling I just add a local physical SIM (not many networks are able to provide e-sim functionality in some of these countries), and set the local number as my primary line for calls, messaging and data. The important thing is that my family, etc, are able to call me on my regular number and don't need to add a new, temporary number. I set up the e-sim pretty much as soon as I was able, and the biggest problem was the fact that my UK network provider's local staff weren't at all familiar with it. indeed, mine may have been the first such setup done at that particular store.

[@mozzyfjre1]

Which network supports esim

[@tomburke5311]

I’m on EE. At the time - last January or February - EE were Apple’s only e-sim partner in the UK, but that might have changed now.

[@214lilley]

Thanks Tom. This is what I am looking at doing, do you know if it's possible to leave the e sim which is my Australian number on plane mode, whilst using my Thai sim in Asia? Or is it easier to just to switch sims in the settings. Any charges that I get from my Australian carrier whilst overseas are huge, so I want to avoid them if possible. Basically what I am asking is, is it possible to have the e sim on plane mode but the physical sim active. Thanks for any advice.

[@tomburke5311]

Mark Roberts Good question. I think the answer is ‘no’. I don’t remember the Airplane Mode switch being anywhere other than in the top level of Settings, which means that it applies generally. Sorry....

[@vincegonzalez9675]

roccow76, HERE’S THE GOOD NEWS: If someone calls your primary number, your digital display will show a “P” which indicates that your caller is calling you on your primary number. If someone is calling your secondary (aka “Business”) number, your digital display will show a “B” which indicates that your caller is calling you on your secondary or “business” line. It works great!!! BONUS: I don’t know how other carriers handle dual SIMs but at AT&T, they allowed me to name each line for Caller ID purposes. I named my personal line “Vince G” and my business line “Victory”. If you’re on AT&T, you’ll be able to do the same. Good luck!!!

[@SWLinPHX]

Only complaint: Still (four years later) there's no option to assign a different ringtone for each line only on a contact-by-contact basis, which does no good for new callers. At least you can see which line they are calling by the little tiny boxed letter atop (P or B, etc.) but I wanted different ringtone, textone and voicemail with my second business line so I can tell without looking which line is ringing. Still going to hold on to my Sideline app, which gives me all those features (+ the second line itself) for just over $8/mo vs. paying for a second line. There are very few glitches after using it for three years. Some things may be better with a built-in second line of course, but other things like dedicate ring & text tones without switching numbers or settings are really nice features and not available even if you do pay more for a second eSIM line.

[@bjoeym]

This feature is now available.

[@SWLinPHX]

@@bjoeym That's good to know. The cost of a second SIM/line with a carrier may be more, but it makes it more doable.
