GSM modem configuration

Hi.

I bought a prepaid regular SIM card yesterday in Montreal (438-345-xxxx).  The purpose was to put it in a GSM SMS controller I got.

I'm having problem to configure it to send or receive SMS and the user manual isn't really helpful.

https://www.google.ca/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CB0QFjAA...

First, I'm not sure what is the format I have to use for the modem to dial correctly:

514xxxxxxx?
1514xxxxxxx?
+1514xxxxxxx?

Also, I have to choose between these bands: PGSM, DCS, PCS, EGSM_DCS, GMS_850PCS, and default (which I don't know what it refers to).  Looking at it on internet just confused me more.

There are many others fields with no explication in the documentation:

-Pin code (don't know what code it's refering to)
-puk code (not sure it would really help)
-smsc number (don't know if it refers to the sim card # or the Koodo service center number, and again, which format the SIM card expect)
-Country code (again, +1 or 1)

The SIM card is tagged "prepaid".  What is different with that card compared with one that goes with a monthly plan?

Any help would be useful.

Thank you very much.

Do you know networks/frequencies this device runs on? Koodo doesn't have a 2G network, only 3 and 4G.

The manual says Dual-frequency 900/1800 or 900/1800 /850/1900.

Can you tell which network it is related to?

I took a quick look at the manual link you provided (dated 2009) and it's probably way out in left field as far as people in this forum are concerned. This unit is designed as an interface for an alarm system, and comes with RS-232 cables.

So don't feel badly if we can't provide much help.

Jonathan is spot on. This device is 2G and won't function with Telus, Koodo, or Public Mobile.

Try Rogers or Virgin as they still have a 2G network.

Also this device has a warning mode for low gsm signal so you should be able to see that it has no signal or that there's an issue.

I can't receive the low signal SMS if there is no signal at all.

But thank you very much, that help a lot, I'm gonna try to find something 2G.

The low signal indicator will show on the computer in the software that controls the modem. It is not sent by SMS

It only shows the set point.

You got it right, it's working with a 2G SIM card.

I would have prefered to stay with Koodo.

Only matters now is when Rogers will stop their 2G service.

Thank you very much for your quick answer, it helped very much.
