Hi there! I am a new U.S. Xiaomi user, and so my new Mi Note 10 Pro has been working flawlessly. My service provider is AT&T, and their SIM card seems to work fine in my phone judging by the fact that I am able to send text messages and make phone calls just fine, as well as use data.However, my only issue is that I have a notification at the top of my screen that has not gone away since I acquired the phone. The notification is from "Xiaomi SIM Activation Service" and it reads:"Find device"Can't activate SIM cardCouldn't verify phone number(see screenshot)If I tap on the notification and click "Try again" to verify the phone number, it brings up a second notification and gets stuck on the step "verifying phone number"(see screenshot)I have no idea what to do. How do I solve this issue so that the notification goes away?Notes & Things I have already triedIn my settings, I have already set my "Data roaming" to "Always."I can confirm that I can recieve international texts, and even texts from Xiaomi, because I have received multiple "verification codes" from Xiaomi with no problem (I use Google Messages for my texting app)I have my phone number connected as a verified "Recovery Phone number" for my account security on the Xiaomi website. It successfully verified my phone number when I added it to my account for security.I have tried restarting my phone multiple times.I am running Android 9 PKQ1.190302.001 and MIUI V1.0.9.0.PFDMIXMHow do I get this notification to go away and successfully activate my SIM card?
