I have been using my Galaxy S6 with Straight Talk. The phone I bought from Amazon, so it is unlocked and just have been using a Straight Talk SIM. Over the past few months I have been getting no service unless I make calls first, so I decided to switch to Cricket yesterday and got the Moto E5. It's a bit slow for the game I play, so I tried putting my Cricket SIM into my Galaxy S6. It works, I get service, can send and receive texts and calls. However, where my LTE data icon should be I have the letter "H" and every time I start my phone, a SIM icon will appear and says This is not a Version Wireless SIM card. How can I get rid of this message, and what's the deal with the H over my data icon?
