These Option cards are listed:
Option Qualcomm 3G WCDMA Model M00201-10886 miniPCI-e
Option Qualcomm 3G CDMA Model M00301 (GTM380) miniPCI-e
The latter (GTM380) is easy to find in the current Option product line
The former appears to be the (previous?) model GTM378, right?
Are there variations of this card? In the list it is mentioned as M00201-10886. M00201 appears to be the model number on the sticker: http://eastar4.com/ebay/OptionGTM378-1.jpg
But what is the 10886 suffix?
Is this the one, or can I go wrong by ordering one of these?
if it’s stuck on “dialing out” then it’s probably either an incorrect dialing string, or a problem with the 3G operator. You could ask them for help. RouterOS only does one thing - discovers the 3G card and allows you to send dialing commands to it via the PPP program. The rest is up to the modem and the 3G provider.
What I have in mind is something like the wiki article for the Huawei E220.
Although these strings were made for a Latvian provider, they worked fine for me here in Norway.
Do you believe that they will do for the GTM380 too?
I know from experience, that these strings are different even for different latvian providers. you should contact your 3G operator technical team and find out
