Do Not Trust!!!!!
I activated roaming for a trip overseas last month. Before returning, I made sure to deactivate roaming via the M1 app — I clicked the orange “Deactivate” button, it turned grey, and I assumed that meant it was off. I showed this to my partner. Apparently, that wasn’t enough — you’re supposed to receive an SMS confirmation that roaming has been deactivated. I never got that SMS, which means the roaming was still active without my knowledge. The next month, I was shocked to see a full roaming charge of $68 on my bill. Before calling M1 customer service, I double‑checked the app again — the button was grey, showing “Deactivated.” I thought this confirmed it was just a glitch. Unfortunately, my biggest mistake was not taking a screenshot — because during my call, the customer service rep “deactivated” it immediately, erasing any trace of the app’s error. After a full week of back‑and‑forth, M1 insists the issue wasn't on their end, claiming their app has no issue and offering only a 50% refund — even though their faulty app was the cause. This was not my fault, and yet I’m being penalized for their system’s failure. I do not recommend M1 — be very wary, always take screenshots, and never trust just the button status in the app.
