Bulk SMS is basically a platform where you can send thousands of messages simultaneously to targeted mobile numbers with a simple click through different bulk SMS gateways.
English text : single text messages are limited to 160 characters,
including spaces.
Each concatenated text message is limited to 153 characters, rather
than 160 due to the need for user-data headers (UDH) information. Mobile
phones use UDH information to enable them to link long messages together
so they appear as single SMS messages in recipients' phones.
