Our Stats tab helps you to keep track of your usage, so there’s no danger of you going over your plan limit on data, voice or text. (NB – this is why the app needs permission to access contacts and SMS, these are the permissions needed to count calls and texts, messages are never accessed or read!). Slow mobile internet? Whatsapp or BBM not working? Can’t make that crucial skype call? Facebook, Instagram or Twitter too slow to be enjoyable? Run a speedtest to see the real speed of your connection, use the signal booster compass to get a better connection or use our maps to find the nearest free wifi!
