Member: 1759223 Status: Offline Thanks Meter: 13 | 3gs 4.1 gsm signal dilemma IPHONE 3GS 4.1 baseband 6.15, jb and unlocked. It will get full signal on one carrier SIM card and only 3 Bars on another. All should have full gsm signal in my location but it is not the case with this iphone. i know it is not hardware issue like antenna as this phone gets full signal with all other carriers around. I checked Network settings, swapped different sim of the same carrier, nada! I am not sure what the deal is any tips welcome |

Member: 1759223 Status: Offline Thanks Meter: 13 | what do you mean my friend? if i wasnt clear enough let me repeat that the same sim on another phone in the exact same location gets full signal The iPhone is a quad band GSM device meaning that it can use all of the GSM frequencies around the world. The frequencies are 800/1900 (US) and 900/1800 (Europe). |

Member: 163 Status: Offline Thanks Meter: 7,785 | sounds weird, but you should try with another identical phone, on same place, same thing. p.s. 3G network, operates at hihger band - higher band = lower signal so, do the testing with another same device, if showing same, than it's operator low power on 3G network. p.s.2 i had some strange issues with one 3Gs on 6.15 BB, worked normal on 3G, but on 2G being unreachable, customer told me it was working normal before BB 6.15, so consider that too ... b.r.

Member: 1759223 Status: Offline Thanks Meter: 13 | Thanks for the info Alex.Most likely it is the provider here. I should be getting some 3g's shortly and will do some testing. My windows phone all are getting full signals with the same sim card. |
