I currently have the $10 plan with unlimited voice, text and wifi data and no cell data.
My plan no longer exists and has been replaced with the same plan at $15 but I am still on the $10 plan.
My questions: (1) can I purchase a block of cell data rather than changing plans where I can keep my $10 plan and just purchase data when I want?
(2) If I do purchase a block of data - will I keep it for as long as it takes to use it all or does it have an expiration date?
(3) Right now I don’t have any cell data but as I understand it, my phone is using some cell data for making calls, etc. How much of my purchased cell data would be used each month for these system activities? I don’t see a reason to purchase data just to have it eaten away at a high rate for these purposes.
Thanks for any info.
