Have been an ST customer for several years. Been through 2 phones and now on my third. The first one had a glitch and seemed to be dialing folks on the west coast even when it was turned off! Had to change numbers and phones at my expense which was frustrating. The second phone worked well for 2 years. Both the first 2 phones rode on the Verizon network and had good signal almost everywhere we went in the eastern US.
When I had to change out the worn out second phone I thought I had acquired a ST phone that rode the ATT network which should have been OK- but instead I accidentally acquired the phone they recommended for my area which was on the Sprint network. For all practical purposes I rarely have any signal anywhere I go.Now I must change out phones again if i stay with ST. Lesson learned-- be careful which network you connect with through ST-- which is dictated by the phone model you choose.
When traveling to Alaska last year we had no service option with Straight Talk while passing through Canada. We shut down service with ST for that month and connected with ATT on another phone with roaming while in Canada and AK.Started ST when we returned to the south.We're headed back to AK this year and will probably use ST entirely for the trip- with no service in Canada. My son says they have ST in AK now.
