I just installed a free 1GB sim and activated it. Alll features work fine but one. I can make outgoing calls. I get a nautomated nessage.."
Monthly membership run out.
Time to buy a new one."
Yet the data amount remains intact.
You need a membership to be able to make calls and send texts.
The free 1GB data is just for carrier data access to try it out.
It does not cover calls and texts.
You won't be able to make calls or send texts until you buy a membership.
Hope this helps.
