Please reset your network settings:

Settings > General > Reset > Reset Network Settings (you'll lose WiFi passwords).

Additionally, if you have different cases on your phones, they may affect your signal strengths differently.

If you still experience the same issue with the phone after the network reset, I'd visit an Apple Store (if there is one nearby) for additional diagnostics. An appointment is required.

We have the same phone case just different colour , will try the network reset and see if that helps. Was there a issue with the entanas with iPhone SE ? I'm not the only one who had or has issues with signals being very week due too entana issue

Never heard of an issue with the antennas of the SE. I believe Apple learned from their mistakes made in the past

I'm not speaking of any particular issue, just that cases can affect signal strength, based on their composition.

Are both phones running the same iOS version? Go to: Settings > General > About - Version.

Certainly. If you're not satisfied with how the device performs, by all means exchange it for a device that works to your liking. Keep us posted on whether or not this resolves the signal issue.

Okay so I swapped the iPhone SE for another one and same thing. What I notice with the iPhone SE is whenever I have poor signal and when I turn off 3G data off completely my signal increases and another odd thing I found out was Whenever I turn on 3G signal reception drops can't even connect to internet or make a call but when 3G is off I can. So what I did was turn off data completely signal strength increases made a phone call then turned back 3G on and guess what it worked so looks like a software issue between phone and koodo

Strange indeed. I'll see if I can find something that points to or offers a solution to the problem. In the meantime, compare carrier settings versions between your new iPhone SE and your wife's. I'm guessing that since the two iPhones are new, the carrier settings versions should be identical. To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier.

You can manually check for and install a carrier settings update using these steps:
1. Make sure your device is connected to a Wi-Fi or cellular network.
2. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.

Which iOS version is your phone currently running? If the iPhone SE is still on iOS 9.3.2, an upgrade to iOS 10 may solve the signal issue. An iOS upgrade will also prompt for carrier settings to be updated.

Why does the iPhone SE have such bad signal strength on 3G and LTE. Compare my old phone Moto G3 . Moto G3 will work in elevators/ basements but the iPhone SE dosent anyone care to explain? Is it a software issue with Koodo and the iPhone ? Or iOS issue

I highly doubt Koodo would reduce signal to one of their premium phones, so it most likely is due to physical / hardware differences between the phones. Phone design and antenna placement can make a huge difference to reception, as does the radio bands in use. The higher the frequency, the poorer the building penetration. Using 3G instead of LTE may give you better in-building reception.

Hard to guess without being there physically and doing some tests. I have not had the SE personally, but have had just about every other iPhone since the 4 and they've been as good, or better than other premium phones.

One thing to keep in mind that the visual representation of signal strength in your status bar is not standard. One phone could report a stronger signal than another when in fact it could be the same or worse.

You can test the actual signal strength by entering Field Test Mode on phones:
