I had been using my Axon 7 with no sim. I just got my T-Mobile sim today and popped it in. Nothing in the Playstore will update or download. It keeps saying "waiting for network." Everything was working fine before I put in the sim. It won't download/updates even on Wi-Fi now. Still says "waiting for network." Everything else works fine. I can use mobile data for apps and YouTube etc. Issue is the Playstore. I have cleared the data and cache on the Playstore app. I have reset all network settings several times. I have put this T-Mo sim in my unlocked S7 Edge and everything works fine, including downloading/updating apps in the Playstore. I've powered down the Axon, swapped out sims and everything. Playstore still says "waiting for network." Any suggestions before I send this thing back to Amazon?
