What do you mean "didn't like"? did it not work or were there high fees?
I used it on the "Simply Unlimited" plan and after a few weeks the hotspot didn't work anymore as DW had used up all the 5GB included.
So for a $15 more per month I upgraded instantly to the Unlimited Plus plan.
Nicely they only charged me ~$4 for the remaining time that month.
After being in Canada for around 6 weeks, I got a message that I was using the phone a lot outside the USA and the intention was it should be used mainly in the USA.
I'll admit, I signed up only about 2 weeks before our trip as I wanted to test it in the USA and mainly wanted it for the trip.
I ignored the text and continued to use the phone and it worked fine for the next ~10 days until we returned to the USA. No extra fees.
I did make a call as soon as were were in the States, to show I'm using it in the USA.
Then 3 weeks later I cancelled the service as I have my regular prepaid service still.
My good experience with google Fi does tempt me to drop my super cheap but no data plan that costs ~$3/mo on avg and upgrade to google Fi.
