I transferred the service to an old s5 and it works great. Gps\text\calls work fine. The internet is fast. You can use a gig pretty quick, don't watch videos. But it's more then enough it to apply online, look at job listings, fill out online paperwork, lookup phone numbers and GPS.
I would give them 5 stars but the first phone they sent me was garbage, id have preferred a flip phone. The phone they sent me often froze up and filled itself up with memory via its own updates. GPS never worked. When it wasn't freezing up I could make phone calls and text.
Check to see if you can use another phone with this service, mine was not on the list but you can't enter your phones eimd or something like that and check to see if it's compatible. All the info is on their site.
