I am looking for an SMS Gateway service provider with a PHP API that allows me to:
- Send out SMS messages (including small binaries) to mobile phones
- Receive SMS messages from mobile phones
- Send reverse billing SMS text to mobile phone
- Messages can be sent/received to/from mobiles globally (or at least most countries)
- Allow bulk sending of text messages
Ideally, the API should be relatively straightforward an easy to use. Last but not the least, the service should provide good value for money (i.e. it should be inexpensive or relatively inexpensive for the features it provides).
I am (currently) based in the United Kingdom (I dont know if this is relevant in the choise of SMS service provider).
I would ideally like a recommendation from someone who is currently using (or has succesfully used) such a service.
