And I have a Huawei P20, so it is quite an old phone.My brother has also heard of similar situations in the last 2 days from people that are from different service providers as well.
I restarted my phone. I also did a network restart. I have been trying to talk to a PM agent. I am waiting for a response. I also tried using the IMEI checker, but it was saying that my phone wasn't valid or something.
