I started out with Sprint and a Galaxy note 9. Was unable to send/receive texts or calls. Called sprint and went through all troubleshooting over 2 months time, talking to 5 customer service agents, 3 tech support, supervisors and higher tiered agents. We factory reset, did #727__## (don't remember #'s), turned off my phone so they could reactivate it remotely, reset network, no tower outages, sent me a new Note9 (still same problems), made sure no calls/texts were being blocked, they sent me a “Pebble" box to improve network serve (didn't work), my husband is on the same phone plan with no issues. I have been using Facebook messenger to make calls and texts but that doesn't allow me to call business's or anyone not on friends list. Finally I switched to Verizon with an upgrade to the Note 10 and the same phone number. Now I'm able to make/receive SOME calls but still no texts incoming or outgoing. No one can help me or knows what's going on! I'm at my wits end, seriously. Someone PLEASE answer/help!
