DH and I have both changed from Verizon to Straight Talk and have been on the $30 plan for about a year. He did decide to change his phone, i forget why, but they were helpful and it was done very quickly. When my son was in town and there were lots of family get-togethers I used up my $30 in less than 30 days - no problems just added another $30 to the works - it changes the day you have to refill - no problems with the signals. The phones we bought use Verizon towers. They will tell you which phones use which towers before you buy. We were spending about $250/mo on Verizon and locked in for 2 years - seperate contracts we had before we met. Now we are spending $60/mo and are much happier all round.
