I spoke with Telus technical support and they have assigned a case number for their "2nd level" technicians to follow-up on. Agent I spoke with was very polite and helpful. I was put on hold a few times while they consulted with senior technicians.
At first, I was told that Telus is reporting to Apple that the iPhone 5 is only saying "3G" even though it is on LTE when a speed test is done.
However, I informed them that I was able to successfully connect to LTE in Ancaster, Ontario (HWY 403 near Wilson Street) earlier today and did a few speed tests... That is, the phone actually said LTE in the top left corner... Download was 30.04 Mbps and Upload was 13.98 Mbps.
Unfortunately, LTE connection was only reliable while on the wide open highway. Anywhere within the Greater Hamilton area has 3G service only ... 4G is not appearing on the phone's display if no LTE is available.
This, however, is not what Bell & Telus are advertising. They have a very detailed coverage map at http://www.bell.ca/Mobility/Coverage_map ... It clearly shows the Burlington, Hamilton, Stoney Creek area within the 4G LTE service zone, and an even wider net for their 4G HSPA+
My suspicion is that if Bell/Telus send field agents to the area to investigate, they are going to discover that they are not providing the service they claim to be.
For one of my speed tests while on 3G, download peaked at 0.35 Mbps and upload was 0.29 ... note the decimal.
Other tests download at 4.64, 3.22, 4.34, and 4.74 ... obviously not the 4G service claimed to be in this area.
So, is it an antenna problem? ... Or is it a service problem??
Only the Shadow knows.
