this is how it should work

weekend at countryside kind of suprised me… :)

so, Cisco 887VAGW+7-E-K9, a little configuration and here we are.

you’d need to configure profile however. as i didn’t have SIM card and i had poor experience with Orange in Poland, i decided to try challenger - Plus. they had a small sales office in nearby city.

how educated the lady was! i was almost ashamed that not only she understood that SIM card can be used in routers, but she also new nearest BTS locations as well as frequencies!

unfortunately, there’s one single problem - in Plus to verify your limits, you have to receive SMS. of course i don’t like to remove SIM card, put it into my phone just to send and receive SMS… it seems our routers already support SMS operations from CLI:

router#cellular 0 gsm sms view all
[...]
SMS ID: 2
TIME: 15/05/23 09:21:48
FROM: ^@^\%#
SIZE: 30
Plus online: Session password is 14436

and this is the way it should work! by the way, RSSI also suprised me - thanks to the network, average ping time was 60ms!
