I just dropped Consumer Cellular (using an AT&T sim) and ported my number to T-Mobile (I know from experience their service is better here at my house compared to AT&T or Verizon) .... $40 per month guaranteed for life, unlimited talk minutes and unlimited data. Unless you are a high data rate user this will work .... it's how I've talked on the phone and accessed the Internet for the past 15 years. It won't help my speeling, but my posts will be much louder now....
CAN YOU HERE ME NOW?
Compare the three carriers and go with the best service at your location.... it varies.
