for the past 3 days, my phone can't detect any network at all, no matter the location

using Xperia X, data only

i went into a yes branch to troubleshoot, weird thing is his yes4g number can be used on mine, also my yes4g number can somehow used on the staff's phone, in the end came back with no solution

have already tried messing with the apn setting, vpn, the "download internet setting"

anyone know any other way i could try?

*assuming this reply to my question*

seriously? weird, my number still can work normally on other phone, and other yes number can use on my phone as usual

yea i do use hotspot unlimited, total usage are 70GB, and only 7GB are from the hotspot use

if so, they probably ban my phone+number specific combo, damn
