There is away around it.
Pageplus will activate them, but you will lose BIS in a month.
You will mainly have to turn off data on the phone, so you won't be charged. BlackBerry and app's ping the server. Suggest you download opera mini before you port. Some advance phones will need to be manually programmed to work with PP.
Also,
Mingo wireless will be offering a package that will support BlackBerry and app's but their BIS is a little high right now.
Note,
When porting from post paid make sure you do it after your contract has expired, otherwise you have to pay an ETF & the last month usage. (You still have to pay the last month usage either way)
You won't get mobile to mobile minutes Verizon to Mingo/pageplus and from.
No, I am not a spokesperson for either company. I am just providing this information from what I have read about them, in fact I use Airvoice CDMA.
