haven’t had too much time to do in depth research, but had time to compile the following table:
| ClickSMS | BulkSMS | Text Marketer | intellisms | O2 Unlimited text plan | |
| 500 | 4.3 | 4.5 | 3.7 | 6.4 | 2 |
| 5000 | 3.9 | 4.2 | 3.7 | 5.5 | 0.4 |
| 50000 | 3.3 | 3.9 | 3.4 | 4.1 | 0.4 |
| 500000 | 3.1 | 2.8 | 3.1 | 0.4 |
The lowest prices among the SMS Gateway service providers in the UK appear to be for Text Marketer, but even these are from 7 to almost 10 times more costly per SMS than using an SMS gateway device with a SIM that has a monthly SMS plan from a mobile network carrier (in this case a 10 BP/month plan for 50 minutes and unlimited text by O2, and assuming “unlimited” actually means 2500 messages).
