Not sure how many people out there got eSIM working with AT&T on their Fold 3. But 2 or so weeks ago I went into AT&T and got them to get eSIM working on my Fold 3. It's been working great till recently. I think it might have been with adding a 2nd line (Tello).

SIM1 = Tello
eSIM = AT&T

right now Tello works great. AT&T... I can get Text and data but I can't make any phone calls or receive any phone calls. Anyone else using the DUAL setup?? I went in to get a new eSIM and same thing. Can't make or receive call but I can text and receive text and get data.

I have removed the Tello Sim card for good measure. Rebooting a good dozen times and no matter what I can't get AT&T to dial out or get calls.

Any ideas??

i was warned about this scenario by an ATT Manager; he said that the physical sim had to be an ATT sim. i have an unlocked ATT Z Fold 3, however, i haven't tried using another carrier's sim/esim. I also have a network unlocked, ATT S22U with a T-Mobile eSim and an ATT physical sim. phone calls and text msgs work fine, as long as i use Samsung Messages (no the Google version). if i use Google's version of messages, group chats don't always work.

I have an unlocked fold 3 and use a Google Fi physical sim, and had a GSMA (AT&T) eSIM with Red Pocket. Both worked perfectly fine with no problems. Phone calls, texts and data were flawless on both networks.

Google Messages does have an issue it with dual sim. For example while connected to the mobile network if your preferred sim is set to the physical sim, but you try to send an mms with the number associated with the eSIM you will have to switch to the eSIM to send it. Chat messages are effected the same way. Text messages don't seem to be impacted that I have encountered. Receiving messages seems to be effected in the same manner. Google Messages works normally when connected to WiFi and using RCS Chat

Since we can only have one data connection active on one sim at the same time, Google Messages gets weird about it. The issue is not present with Samsung Messages or Textra. Until Google updates the Messages app to fix the issue you will have to either change the preferred sim back and forth, use RCS on WiFi only, use Samsung Messages or use another 3rd party messaging app that has dual sim properly working.

Also be aware changing the preferred sim will also make it the default for messaging and phone calls. For some reason we lack the setting to specify which sim for calling and messaging. So if your eSIM is the primary number you use and switch to the physical sim, all your calls/messages will come from the physical sim. Using the shortcuts i mention below won't fully resolve this either. You can use an app like multi sim selector to help with the calling, but the messages you will have to be aware of what number your messaging from (sim 1 or sim 2) or the above suggestions.




@OP - Might be worth getting a hold of AT&T and asking them to make sure the eSIM is provisioned correctly on your (and AT&T) end. If it was working and then not it sounds like an AT&T issue.

I'm not sure if this applies here, but I've read a few comments on the AT&T forums AT&T prepaid doesn't play well with eSIM. I can't verify that to be true or not since I don't have the prepaid service through AT&T.


Meanwhile make sure you have set the eSIM up properly in the sim card manager. At first my eSIM did not have the APN selected as active, I had to manaually mark it as such... Secondly does the call/text issue occur when the eSIM is set as the primary sim? If so go through and double check the sim card manager settings so you have DSDS enabled.

You might want to get an app like Quick Shortcut Maker and look for "Mobile Network".. There are a few sim manager settings that might help resolve some issues your having. I attached an image to help find the shortcuts.
