So would like to provide an update, I am currently doing a 7 day trial period through T-Mobile and so far so good! Have been getting good reception everywhere I've gone today including my house (and basement) and various places around my city. Haven't dropped or missed a single call or text yet so definitely seems very promising so far. So from what I've gathered so far this phone and Straight Talk bands just don't mesh well, but all has been fine thus far through T-Mobile. Appreciate the suggestions LP and Anders, looks like this phone will be staying with me afterall.
