Prepaid - Long Validity - Free/Cheap Data GUIDE
Good for Kids, Parents, In-Laws, Backup

I've been doing some research regarding the cheapest way to get extended validity and at least a slow speed data plan. All with minimal cost. It's an ongoing process so still a lot of ???. In my case it's for my kid who won't be making many calls nor accessing the internet except on wifi but would love to have Whatsapp active constantly. In other words, my criteria is (1) extended validity followed by (2a) slow data plan or a (2b) cheap fast data plan. I'd also like to avoid Data PAYU entirely.

Here's what I have so far. Any additions, suggestions or corrections welcome.

Who is this Guide for? People looking for:
1) Long validity and a free slow speed data plan for minimal expense. Reload and forget once a year.
2) Long validity and a cheap long validity data plan so you don't have to reload every month.
3) Long validity only with no data plan. Good for backup phones. Avoid Data PAYU for this or turn off mobile data.
4) Long validity data only plan. Good for tablets. Coming Soon.

Notes:
- Voice/SMS Rates are off-net.
- Voice calls are listed for 1 min calls. Actual charging blocks varies.
- Plans and rates change constantly so always double check.
- Only plans with voice are listed. Might add data only plans later.
