any Bell/Telus towers around the area?
When looking at the map the closest telus tower only has the 2100mhz band so you are connecting but not with other essential bandz for full services. There are bell towers that you could connect to but they may be a little too far away and/or your phone is seeking the nearest and best connection which is the telus tower. Try forcing your phone into 3G and this may allow your phone to seek a connection with the bell towers for service. ( The nearer rogers tower will not connect as there is no sharing agreement with telus....only bell and telus have sharing agreements.)
@darlicious the Telus site is an indoor one. Port Bruce seems like an area with no coverage on the Bell/Telus network.
Edit: I should say poor coverage area instead of no coverage area.
So the bell towers are too far away to connect to? If I read the OP's post correctly why would there still be service bars on their phone while in Port Bruce?
Looks like that telus site is at Jaffa Machine a steel fabricating business.
@darlicious They don't seem to be too far away that it's completely out of range, but depending on the terrain, signal may be unreliable in Port Bruce. Seems to be 10-15km away eyeballing it
@softech not necessarily related to the frequency band, but this area of Ontario is Bell territory. All outdoor sites are Bell.
That does look like that is the problem. Even though the towers are at 200m+ in elevation Port Bruce lies in a river valley that dips to as low as 180m. Valleys do not serve well for cell service connections. The nearby rogers tower could even have dead zones depending where you are in Port Bruce.
Unless you spend a lot of time in Port Bruce ( live there?) you will have to be resigned to having little or no service while you are there. If you have a friend with a rogers/fido/chatr sim card you could always try that in your phone to see how well it connects to its tower while you are in Port Bruce.
Most likely you have access to lte tower but they are lacking any 3g towers in that area. In that case you would have access to data and texting but not calling. Ib would suggest using Fongo for Canada calling in such area or TextNow is you need access to USA calling, as Publicmobile doesn't support VoLTE yet
