Hi Thanasis, Sorry for the long delay in getting back to you. I've been very busy working with other aspects of my business start-up. Just to let you know, I'm going with the USB GSM dongle option for now. I may look into getting a tablet with a slot for a SIM card in it to avoid needing the external USB device at all.
I tried a couple of Huawei modems which worked but with some awkward side-effects, namely the E160G and the K3765. Side-effects were random disconnections (something related to Java Comm I think) and StringIndexOutOfBoundsExceptions while reading new messages. The one that works perfectly for me now all the time is the Huawei E173. No special modifications required to make it work. It's good news for me because Meteor (a mobile phone company in Ireland) sell a refurbished (second-hand) E173 for just €9.99 - http://www1.meteor.ie/mobilebroadband/payg/ Regarding the read and unread messages and the problem of only wanting to get unread messages, I have finally taken your recommended option and now I just delete messages from the modem once they arrive and have been read by SMSlib. Anyway, thanks for your help so far and for making your library available. By the way, I hope you're satisfied with the results of the Greek elections last weekend. More importantly, Greece did brilliantly to get to the quarter-finals of Euro 2012. Ireland did not do so well :-( Best of luck against Germany tomorrow night!
