Galaxy S6 / Cricket

[BadBlood7984]

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?

What's the exact model number of the phone? Different variants may support different LTE bands, and it's possible your variant doesn't support Cricket's bands.

Also, make sure the APN settings are correct for Cricket. https://www.androidcentral.com/what-apn-and-how-do-i-change-it
