Top right corner is nothing but saying searching. I can't message or call nor incoming. I've restarted my phone, took out the SIM card and put it back in. I'm getting super upset trying all these options and nothing seems to be fixing this
Are you in a location where you are certain service is available? If so, it is possible your SIM is bad and needs replacement. If you do not know someone who is a Koodo / Telus subscriber with whom you could test-swap your SIM, the simplest step might be to stop by a Koodo shop and ask them to check for you.
What phone do you have? I've been having the same issue for the past week with my iPhone 6s. I replaced the sim card twice, and I went too the Apple store where they told me they don't know what's wrong with the phone and offered me to get a new iPhone 6s for around $400... Very weird and frustrating.
