Bulk SMS API & Number Provide

Hello,

Can you suggest me Bulk SMS Service Provide, that Provides:

1. Geo Long Number (123-321-1234)
2. Incoming/Outgoing Calls & SMS.
3. SMS API for Autoresponder. Receive SMS & Reply to that SMS.
4. No Limitations & Low Cost.

I see many service provider but not getting the desired service.

I would be grateful, if you suggest be the best service.

Thanks in Advice.

Is it fine with android app? you can try our iMarketing Center app. This app has sms auto reply (base on keywords), auto subscription (also base on keyword) and unsubscription (base on keyword also).

You need to use your sim card to send and receive sms. But if you are in country that Twilio support, you can use Twilio also. (Twilio is a cloud based sms service).

You can register for monthly usage or purchase the app. It's cheap compare to all the other app/service that have those features

I was trying Nexmo some time ago. Almost all GEO locations, gives API and so on. SMS and VOICE numbers, I guess its all what you've asked. And price is relative thing

I know Nexmo also, but it's not as good as Twilio.

As I read, Nexmo only support up to 250 messages per day but Twilio is 3600/h
