Hey everyone. I recently bought a used HTC Evo 4G LTE and signed up for Straight Talk using the CDMA Bring Your Own Phone activation kit. Everything works great, but I keep losing 4G LTE. I'll get it for a week after calling the Straight Talk peope up. They have me turn the phone off, they do something on their end, I turn my phone back on, and update the profile and bam, 4G LTE. This only lasts for maybe a week until I have to call again to get 4G going again. I am on Viper4G 3.1.7. Could this be why I keep losing 4G? I don't know. Any help on this matter would be so appreciated. Straight Talk customer service can only get me so far. I thank you.
