Hi guys
I need a GSM Modem with external antenna support that works on at least 3g
(2.5g may be acceptable) in the US. I bought a bunch of them online from other countries. I brought some huawei E330 modems from other countries, and I only seem to be getting a 2G signal here in USA. Can anyone please give me a link to buy good 3G/4G modem that works in USA ??
Would be ideal if linux (raspberry pi in particular) automatically
detects it as an ethernet device and has some easy method to grab sms
messages from the modem.
