I’ve had FreedomPop on 2 phones for more than a year. I haven’t paid anything extra, just the 200 free minutes, 500 texts, and 750 MB per month. You just have to know how they operate (as in, read terms and conditions. . . .)
I have multiple things on the phone used the most (which is low use by any standards). Besides FreedpomPop for cell phone/data connection there is MagicJack that matches the number for the MJ connected to the main phone line at home and then the Google Hangouts (whatever it is) for yet another means of dialing out. I’m not dependent upon the phone for my survival. If it is important people and send or leave a message.
One thing I did find out is that in the last year sometime they changed the the switching to the free setup from the introductory SIM card (99 cents or 1 cent) to require a $5 credit on the account to go down to free. I got a couple extra SIM cards for 1 cent thinking I’d just have some spares, but then found out they wanted $5 to downgrade. Those were just cancelled and nothing paid other than the initial 1 cent. But the 2 originals are still working fine in 2 phones.
Another thing of interest is that if you don’t call anywhere and use no minutes in a month they charge your card on file 1 cent. I have no idea why, but it is there in the terms so I make at least 1 call each month. I also don’t know why they need any $5 to downgrade, because they have your credit card info on file, so what’s the big deal in holding $5? Their biggest problem is that they don’t specify how things work clearly and act like they are trying to take advantage of people, when if they just spelled things out and worked at it it could easily prove a better way for a lot of people.
Also, MiFi things work wonders (nice eBay ones) for 3G data.
Often I use the 4G data from FreedomPop to make MagicJack calls. For some reason at times it doesn’t even record the MB of data used. Strange.
