My contract for my iPhone ends in November and I'm considering canceling my plan. I only have 500 minutes and no texts and am considering using that money toward a larger data plan (maybe 5gb, currently have 3gb data). I will then port my number over to Google Voice. Has anyone tried to do this? If there are threads regarding this issue, I didn't have time to search through them.
Edit: I probably wasn't clear enough, but I'm looking to get a tablet data only plan and use it in my phone. AT&T does not prohibit this, though AT&T does not approve of the other way around (iPhone/smartphone SIM in tablet).
I would say the experience is not the same using google voice....because you cannot accept incoming calls on google voice unless you use google hangouts on your iPhone (I have been using it temporarly and I would say the experience is *****) Google voice no longer allows apps like TalkaTone that allows you to make and receive calls via google voice using a app....
If its something you want to try out, I would say try it out but don't go as far as porting your number out to google voice (its $20 + another $20 after 90 days to make it permanently stay with google voice unit ported out post the 90days)...instead try to use it side by side and see how you like it for at least a moth...since you don't use as many minutes I would say 1 month will give you good feel for it.
I would recommend trying out services like AIO or the new Cricket plans that give you larger data pools for a pretty decent price....
Also simply avoiding watching videos over cellular data can make 3GB plenty...only time I find my self using plenty of data is ONLY when i watch videos, streaming music (8hrs/week), google maps (100-150miles weekly) and ton (50+ mostly without attachments) of emails on daily basis only take me as far as 2-3GB max.
AIO / Cricket sims will work on a AT&T locked iPhone since they are now all owned by AT&T.
