The Benefits of Bulk SMS ME - W2WTS’s Bulk SMS Gateway API:

Our API (Application Programming Interface) makes it easy and cost-effective to integrate bulk SMS messaging into your applications. It offers:

SMS to multiple mobile numbers in one Go : Our SMS API allows you sending SMS to multiple mobile numbers in one single call/request. You can do this by passing comma separated numbers to the mobilenumber parameter.
Communication via SMS in any language : Our SMS server supports standard GSM character set and Unicode characters, so you can send and receive text messages in English, German, Arabic, Russian, Japanese, Chinese and more.
Support for FlashSMS : You can send flash messages using the API. The messages will get delivered to end user mobile as a flash and will not be stored unlike normal messages
Send WAP Push URL messages : Send your direct application download link or your mobile site link to your users using our WAP URL Push supported API. The clickable link will be delivered to recipient mobile.
Custom/Dynamic sender IDs : When sending texts via our HTTP SMS API, you can display any of your registered mobile numbers/senderids as the sending number, use your own mobile phone number, or use a sender ID, such as your company name. Note: Which ever senderid you submit via API must be registered and active in your account.
Delivery rate tracking of your SMS : You can request delivery notifications of all sent messages. All mobile phones return delivery notifications and you can get them via our SMS Gateway web interface.

API for Arabic + English (AnyLanguage/Unicode/Language/Non-English) Message text

API For sending SMS in Multi-Language text (English or Non-English or Arabic or Mix, 1 to 10 numbers only in each API request) :-

http://sms.bulk-sms.me/API_SendLanguageSMS_2020.aspx? User=demo&passwd=demo&mobilenumber=xxxxxxxxxxxx&message=Welcomeأهلابكالإمارات&sid=Test&mtype=OL&key=GeneratedAPIKeyHere

API For sending SMS in Multi-Language text in Unicode form (Non-English/Arabic/Unicode, 1 to 10 numbers only in each API request) :-

http://sms.bulk-sms.me/API_SendSMS.aspx? User=demo&passwd=demo&mobilenumber=xxxxxxxxxxxx&message=062A06450020062A0633062C064A06440643002006280646 &sid=Test&mtype=OL&key=GeneratedAPIKeyHere
(Click here to test)
Note : message=<Unicode converted value of actual message>
Message needs to be converted to unicode (Big-Endian UCS-2) before passing to the API. Ex : Unicode for arabic character beh ب is 0628, please refer the following unicode chart.

API For sending thousands of SMS (For Arabic/Unicode message, 1 to 50,000 mobile numbers in each request):-

http://sms.bulk-sms.me/API_SendBulkSMS.aspx?User=demo&passwd=demo&mobilenumber=xxxxxxxxxxxx,xxxxxxxxxxxx,xxxxxxxxxxxx&message=062A06450020062A0633062C064A06440643002006280646 &sid=Test&mtype=OL&key=GeneratedAPIKeyHere
Note :
message=<Unicode converted value of actual message>
Message needs to be converted to unicode (Big-Endian UCS-2) before passing to the API. Ex : Unicode for arabic character beh ب is 0628, please refer the following unicode chart.

Number of characters & SMS Credit & Billing

1SMS Credit = 160 English text Characters, where as 1SMS Credit = 70 Arabic/(Non-English) text characters.
