Me too. I have to go near our window on our second floor to experience fast mobile internet. I have been asking Globe regarding this through their twitter support. They just kept asking about my number, location and etc, and they would then confirm that there was nothing wrong within our area. My device is perfectly fine. In other areas, its mobile data is very fast. I think we need some sort of Globe signal repeater or booster around our location to solve this.
I'm currently subscribe to Globe Unli Data with Samsung S3 phone then I experienced slow mobile data. I tried to change the mobile network settings to WCDMA only instead of GSM/WCDMA (AUTO MODE) then my mobile data is now faster than before.
