I"m working on an app that uses text messaging (SMS) in an embedded application and I'd like to source a SIM card where I just pay per text (dont really care about the rates) but I refuse to pay a monthly fee for it. Does anyone know of any SIM card suppliers where I only need text messaging and am willing to pay a lot for it ($1 per text) but no monthly fee.

Where are you from? In Italy you could easily buy a prepaid card with an average price of 10-15 cents per SMS... –  clabacchio Jan 24 '12 at 9:20

This is prepaid plan. However you must bay some credits (even if you have a few left) every month (that maybe different period in various carriers) to keep Your account active. But You can spend all credits for sms so technicality there isn't any "monthly fee".

But I think much cheaper and reliable solution would be using some Internet sms gateway for example http://www.clickatell.com/.

The clickatell.com seems to be primarily for internet SMS gateway. I need to be able to send/receive messages only using SMS (not internet) from my application. –  Seidleroni Dec 27 '09 at 15:34

Can you not just get a pay-as-you go SIM card (which is possibly what msawicki is suggesting)?

Or in the UK I'm fairly sure that you could also get a SIM card from one of the networks on a pay monthly tariff (not expensive if you only go for the SIM) and pay about £5 a month for unlimited (sort of) text messages.

I was looking for a similar type plan but could not find one in the U.S., the cheapest one that I found was by boost mobile. You still need to pay periodically but its only every 3 months.
