Hi folks, hopefully someone can help me with this. I run some family events at a large church in the UK. I am looking to start using SMS marketing. I don't want to sign up to service - I want to do this myself. So what I'm looking to do is buy a GSM modem and use an appropriate software package to send / receive messages. But where I am stumped, is in finding a suitable SIM card. Does anyone sell SIMs designed for the bulk sending of business texts, without caps or restrictions? Is there a name for this type of SIM so that I can google search better? THANK YOU!
