With that said, the service has been fantastic and calls work everywhere. I don't have any complaints on the coverage as I can honestly say it beats out the Sprint postpaid I had for the last 3 years! Sprint kept going in and out and data was so slow at times that I wouldn't even want to use it. Not to mention I would get voicemails without calls a lot on Sprint. So as crazy as this may sound, Simple Mobile prepaid is better for me than Sprint postpaid all over NYC!
Simple Mobile 4G plan is throttled to 2.0 Mbps though max - they are absolutely not providing the speeds that T-Mobile provide. I have friends with T-Mobile who get really great speeds here in NYC so there is something going on with Simple Mobile.
I haven't found any info on Straight Talk with a T-Mobile sim but I think it will be very similiar to T-Mobile prepaid as far as speeds are concerned. Maybe they will throttle and not suspend after 2 GB? I wonder if anyone can answer this. It does make sense to pay $45 instead of $60 and get roaming and perhaps better speeds on Straight Talk than Simple Mobile. Should be a smooth transition for you. Do keep me updated on how it goes and how the speeds are. Also, has Simple Mobile ever shut down your data? I'm approaching 1 GB soon and it's almost 10 days into the cycle.
