Has any had this issue? I bought the S10 Tab+ from ATT, with unlimited data international. I travel to Mexico often and my S24 Ultra is connected to the same network (ATT Mex) as my tablet. Guess what? I can't get any data here. Apparently the tablet is locked at 5G making it useless. We've tried everything; reset network settings, new eSIM, add an ATT AP (gets blocked), called ATT. I was told to contact Samsung but they don't control the net. My tablet says "ATT" in the corner but won't work unless on wifi. Of course it worked in the US.
It seems like your tablet might be having trouble connecting to the network in Mexico due to compatibility issues. Even though your phone works fine, tablets can sometimes be locked to certain network bands or settings by AT&T, which could cause problems with roaming. Double-check if international roaming is active on the tablet, and try switching to 4G/LTE instead of 5G in the settings. If that doesnāt fix it, AT&T might need to clarify whether there are any restrictions on tablets for international use. It could also be worth checking with Samsung for additional support.
That's the problem, I can't toggle 4GLTE, there's and option to turn of "5G Standalone" on the tablet but it doesn't force a connection to anything else. What's interesting is when I was troubleshooting with AT&t when I installed a new esim it turned on 4G but immediately went away and never saw it again. I feel like that confirms that their intentionally blocking 4G when the tablet appears capable of getting the signal
