    iOS 13 Dual SIM Cellular Data Switching works great!

    I didn’t know about this feature until the release. What is does now is allow your phone to automatically switch from your primary cellular data SIM to the secondary when it loses service on the primary line.

    If you have WiFi calling enabled it will also route your phone calls and texts through the secondary data line automatically.

    It’s almost like your phone can turn your second SIM into a true roamer network.

    I know of several areas where AT&T has no service and Verizon does and vice versa. This will be awesome for that since now I won’t miss calls and the phone will do the work of switching data providers automatically!

    Yeah, that's been a fantastic feature.. as AT&T in my "home" city (I work for an airline) is not that great... but this allows verizon to pick up the slack when needed!

    Good info, was wondering about this. I can definitely see this coming in handy, especially for international use as well.

    Just added a Tmo eSIM to play with along side my AT&T SIM. Was planning to add Verizon, but the eSIM IMEI in my Apple branded phone is not whitelisted. I’ll have to visit a Verizon store eventually.

    One thing I did notice as soon as I added the eSIM the new iOS 13 family personal hotspot sharing options disappeared. Not sure if this is a bug in the iOS (13.1.2) or by design.

    So no additional SIM slot is required for this ? So damm cool. Wish Android would take up eSim.

    This is great though I would love to hook my moms phone up to another esim for when she travels to the seldom location in New Hampshire without At&t service.

    Yeah I really like this feature. I’ve not noticed the WiFi calling working. Like the phone does not say WiFi calling when att has no service and my Verizon sim does but I wonder if it just does it in the background.

    You have to go into Cellular settings and enable WiFi calling for each line then it should work.. mine says "AT&T using Cellular"

    That is very cool.

    (Android, you need to catch up on this feature.)

    What an awesome feature of iOS 13. I didn't know this. Thanks for sharing!

    If you dont mind me asking, what do you pay for your two plans? When I looked each would require about $60. I would like to have two providers but would only need the Verizon line as a backup.

    Verizon can be prepaid or MVNO. I use now 60$/year Red Pocket on Verizon (100 min 100 sms 0.5 Gb/ month eBay plan) as my backup line, when I go through Maine where my postpaid Att doesn’t work. During past year I had to buy once additional 1 Gb for 10 $. So the total is 70 per year.

    OP, thanks for the good information.

    Not nearly that much. My parents have a Verizon (February UDP) Account and I have an original AT&T Unlimited Plus account.

    We have a trade deal. They use two hotspots on my AT&T account for Internet at their house and our family cabin ($20 per line) and in exchange they give me a Verizon phone line and a Verizon iPad line which costs them the same $20 per line.

    The cost to me to add AT&T as a second SIM is only $20 more than what I’d already be spending since I have an Unlimited Plus account.

    With a bunch of bundling and shared logins between us for HBO (included with my AT&T), YoutubeTV, Netflix and Hulu it makes some sense price wise.

    I have an old Verizon loyalty plan that has unlimited data out the door is $21 a month. I’ll never let it go. Lol. My mainline att line is the old unlimited plus plan which is $25 after taxes per line except for the first line.

    On the red pocket (verizon mvno) line, do you get VoLTE, VoWifi, Visual Voicemail, CDMA (where there is no LTE) on your device - also what device are you using. I too am considering adding a verizon mvno like TracPhone or RedPocket.

    Hi,
    Redpocket doesn’t have volte or vowifi. You can activate vvm by contacting their chat support(I never did that though). They have CDMA. Now I use them in iPhone 11 max pro.
    I used RedPocket a lot on Maine where Att doesn’t even have roaming.
    I just refilled my service for the next yrar for 54 dollars on the eBay.
