I picked up a Straight Talk Bring Your Own Phone kit this weekend to give the service a try on my Verizon 5S. I'm able to make calls and data is working but I'm not even getting 3G. Data indicator says "E", speed appears to be 1X like. The kit claims 4G LTE. I've been through the directions 3 or 4 times with same result. Hoping someone may be able to point out what is wrong so I can get 4G/LTE working or at least some ideas. Thanks.
