Wondering if this phone will work on Ting. The chat support says it will, it shows coverage with T-Mobile. Are there any additional APN settings to know about? Currently using this phone with consumer cellular, which uses AT&T here in my area, and lately their service is getting bad. Just curious before I make the switch to Ting. Presently live in the hill country in Texas. Just a couple of bars on the bandwidth would be an improvement.
