Telecom XT has made bold claims about their new mobile network being “faster in more places”, which has apparently been independently verified. I was interested to know how good performance in Dunedin was, as this is where I live, and I had heard of a lot of problems with Vodafone 3G coverage in Dunedin. As an example, a friend once told me that he could make a video call from one corner of his house, but loses 3G coverage anywhere else in his house. Coverage has probably improved since then, but having acquired an iPhone 3G after a long time using an original iPhone, I decided to test speeds around various locations in Dunedin City for comparison.
XT vs. Vodafone 3G Test Methodology
I took one iPhone 3G, running 3.0 jailbroken but without any jailbroken apps installed except for SBSettings. The iPhone had the XT carrier bundle installed, made by my good friends at iphonewzealand.co.nz. I used my Vodafone SIM card, and ran this against an XT SIM card, both on prepaid. I ran the speedtest.net iPhone app on one SIM, then switched SIMs and ran the test again, from the exact same location. Sometimes the Vodafone SIM was run first; other times it was the XT SIM. Before running the Vodafone SIM, I ensured that the 3G on the phone was reset in order to eliminate any problems the device may have switching from 2G back up to 3G after dropping back.
