I have a dual sim phone, where one sim card is for a standard plan with calls, sms, and a limited data transfer; exceeding that transfer incurs extra fees. The other card provides unlimited data transfer (no calls etc) but I need to type a captcha for it to work for an hour, another hour, another captcha.
The unlimited data one is good for watching videos or browsing the net, downloads, updates etc, but if I want to have email notifications 24/7 I must switch to the limited one - and watch my usage, and remember to switch again before any heavier use.
There are quite a few mobile data monitoring apps, but all I found so far tend to bundle usage from both cards into a single pool, making them useless in determining if I'm approaching the limit on one cards. Can you recommend one that can measure usage per card? A widget for the home screen would be a plus but isn't necessary.
