Mine does. In a shocking discovery, apparently my bill for Globe is now around 8,000php. That is soooooooooooo BIG that I now hate Globe. I called their CustHelp (211) and the agent there did not help solve that problem.
So the problem is the Wi-Fi.
The Globe CustHelp via 211 did not tell me this but good thing the people at applei.ph community told me about “Kahit naka wi-fi ka, pag nag fluctuate yung wi-fi, automatic mag co-connect sa 3G yung iphone” (even if you are using your wi-fi, once the connection between your router and iphone fluctuates, your iPhone will connect to the 3G service.)
What to do?
iPhone users, who are fond of connecting to the internet through their home wi-fi should change the APN settings to make sure you will not be billed by Globe or SMART on internet use.
How?
1. Go to Settings > General > Network
2. Change APN from internet.globe.com.ph to something like fake.internet.globe.com.ph
3. Reset your “Usage” for Cellular Data Network.
4. Connect to the internet via wi-fi and check if your “Usage” doesn’t get any bytes.
Once you have confirmed that you can connect to the internet through your home wi-fi without the Usage getting any bytes, then you won’t be getting those WHOPPING POSTPAID BILLS anymore.
