not that bad.... i also transferred from verizon to tmobile last year for getting a fancier cellphone (what a stupid reason......woman ah woman......).... just sometimes no signals here and there (especially when u wanna use it for sth emergency), like went skiing--no signal, subway--no signal, somewhere rural--no signal, basement--no signal....where my old verizon always had signals everywhere....

well, the plan of tmobile is pretty good which i got 39.99/mo for 1000 unlimited anytime and unlimited nites and weekends, plus the 6th month free. u can simply call tmobile following instructions in fatwallet to upgrade to this plan. however, never used more than 500 mins total each month....
