Dual sims and data in Mexico
We are travelling to Mexico in a couple of months. I know our Unlimited plan includes phone/text/data in Mexico & Canada, but I have read here that the data rates are super slow (like 0.1Mbs/s). Our phones aren't unlocked, so we can't just buy a Telnet sim and put it in, but they have eSim/dual sim capability (which is something I am still trying to figure out how to use).
Does this mean we could buy eSims from Telnet and use AT&T for our phone/text and Telnet for data while we are there? The phones are Galaxy 22 Ultras if that matters.
