New Phone, Old SIM, Network Connection Failing/Dropping

[KimAnderson]

Hi there:

I've been through multiple posts (at least 20), multiple attempts at fixing (at least 10), and cannot stay connected to network.  Please help if you can.  (First post was deleted but I'm trying this again.) 

New phone: refurbished Galaxy Note 20 5G

Old phone: refurbished Galaxy Note 20 5g ULTRA

Can't stay connected to any of the FOUR networks I see in settings.  Network Operators choices are:

1. Fido ("Registering on Fido..." with bouncing/breathing green/blue dots for 2+ minutes.  Followed by: "Unable to connect. Try later." - OR - connects then drops calls / doesn't send or receive texts.)
2. Fido-EXT (Either connects then drops calls / doesn't send or receive texts )
3. Fido-EXT (Either connects then drops calls / doesn't send or receive texts )
4. 302131 (didn't try connecting because it seems sketchy)

Living close to CANADA/US border but not so close as when using the old phone (Galaxy Note 20 ULTRA).

Had to make some network setting changes when living on/near border previously, but don't remember what those changes were or how to repeat.

Here's my questions:

1. How can I get and stay connected to the network?
2. Why 2x Fido-EXT networks? 
3. And what's 302131 network?

Thanks for any helpful info you might be able to share!

Sorry, more info:

When I follow the tutorial for this phone, none of the solutions cause the phone to be and stay connected to the network.

Reset mobile network settings yields differing results, from long delays (30-120seconds) between responses from the phone (to draw pin pattern, especially), and several times, the phone just didn't respond to pressing the Reset button at all.

Extremely long dial times (20-60 seconds) before connecting (or dropping).

Spotty sound / gaps in transmissions IF connected.

Dropping calls.

Now I'm getting a couple new error messages while trying the exact same steps:

Fido network not available.

Unable to connect to Fido.

Failed to register.

Any helpful information would be deeply appreciated.  I've been at this for a good 8 or so hours, and I'm getting nowhere with it.

Holy smokes.  SIM card status is switching between connected, suspended and disconnected.

I'm really lost here....!

Hi @FidoValerie :

Thanks for reaching out!  Here's the information you're asking about:

Location: N7M 6H4

Have reset network settings multiple times with varying results. (See previous reply.)

Model name: SMN981W  (I don't knw how to find model number, or if Model Code is relevant)

[FidoValerie]

You should be able to access our network from where you are, but there might be an issue with your SIM card or device.

At this point, I would recommend reaching out to our Tech Support team so they can look into this with you! 
They'll be better equipped to check where the problem may originate from, and how to resolve it.

Thanks, @FidoValerie ~ I'll give that a try.
