Roaming in Mexico doesn't work

I'm on a roadtrip and my roaming worked fine in US and when I crossed the border to Mexico I received the "welcome to Mexico" message and the roaming worked good for about 1-2 hours, but then after that it stop working, I already checked the settings and turned off/on the roaming and the device but I still have the same problem, the roaming is not working. I had a similar problem a few weeks ago and it was something about my account or that's what the support team told me
