Issues with network coverage

This is rather complicated to explain so bear with me. I got a new phone from a friend who bought on ebay thats been basically been sitting in a box. Since my nexus is all smashed up and broken, I would like to use this phone until my koodo tab builds up enough to get a better phone. I tried putting in my sim card, I get a message saying "proactive command rejected by ME" under sim options. After doing a bit of research I find out that the reason this message is occurring is because the SIM architecture is different than what the phone is used to. I look at the specs of the phone online it says GSM quad band 850/900/1800/1900 (typically Canada networks and telus/koodo work under 850/1900) so technically the phone should be receiving call and messaging signal. The phone however does not support 3g. Quite honestly this isnt a concern for me because I do not use mobile data, I even asked koodo to block mobile data because I like my plans to be cheap, and i use Wifi most of the time anyways. The phone recognizes the SIM, takes the contacts off it perfectly, even knows its own phone number but says No service. I pop the SIM card back into my nexus (my old phone) and go under the "status" tab. the phone says under mobile network that it is running under UMTS:3 which is why I'm "speculating" this is the reason the other phone wont work, because even though I don't have any mobile data per se, im still using a 3g network. The phone is unlocked, I know that for sure. I tried doing the IMEI test on the koodo website and it says that the phone should work on the koodo network. Is what I'm saying on the right path? Is it because of the UMTS issue that the phone doesnt work? Is it possible to revert back to 2g technology with koodo? Because like i said, I really dont need mobile packet data...i just need my phone to receive and make calls/messages.

Which phone do you have?

UMTS 3 refers to band 3 which operates on 1800 MHz. Koodo does not have a 2G network. I don't think your device is compatible with Koodo's network. We'll need a little more information about the phone to troubleshoot or research further.

Its an H-mobile F1. I doubt your going to find very much on it because its a cheap china built phone that was also adapted for north America and only sold on cheap sites.
You can find specifications on it here if this helps:

I just assumed it was cheap because of (really) low end hardware and no Google certification, guess i was wrong.

Just took a look at the specs, Rikkster is Correct, this device isn't compatible with Koodo

I'm just curious to know how you guys can so easily see what I'm missing out on. I simply don't understand why this isn't compatible (you can get technical with me, I actually do quite a bit of cell phone repair and change roms quite often so I know a bit about smart phones and carriers and basebands and what not). Is it simply because its GSM? because i was under the impression it was the bands we use in North America that must match with the phone

We've been doing this a while too :-) . But GSM 850/1900 isn't the same as umts/hsdpa 850\1900

Unless the specs specifically say 3G or hspa or umts, then it's likely 2G(but I didn't know that until I started answering questions here)

Stick around here, you'll learn all kinds of things.
