Review on Affordable GSM SIM Card Plan For Smartphones - 30 Days Unlimited Text, 500 Mins Talk, 500MB 5G 4G LTE Data Nationwide Service by Chris Cooper

Got this for when my parents visit from outside of the US. Initial web set up on Speedtalk Mobile's website did not work (minus 1 star), but an email to customer service took care of this issue. I was expecting a poor customer service experience, but it was surprisingly easy and quick to fix. I'm in the DC metro area so cell and data service was good as expected via TMobile towers.I was getting AT&T prepaid SIM cards for whenever they visited but this prepaid sim is much more economical. Saved over half and it's very convenient to get this delivered as opposed to going to the ATT store. I will definitely go this route in the future as well.
