We are pleased to announce that from now the [High Volume SMS API][1] supports unlimited batch size. This means that there is now no constraint on the number of SMS that you can send with High Volume A2P SMS API. This also means we take care of Queuing the SMS also. We use streaming so we can literally support unlimited batch size

**Features Added**

1. Unlimited SMS Batch Size - Send any amount and volume of SMS in a batch
2. Queuing
