SMS is Still King
6 Most Popular Use Cases for A2P SMS

Mobile Services

SMS is undoubtedly the most widespread usage of mobile phones

Mobile devices have become such an important part of our everyday life that one could wonder how we ever lived without them. With over 7 trillion SMS sent per year, SMS still remains the core component of a mobile phone, and in fact, text messaging is probably the most popular App ever invented.

In spite of the fast growing usage of Apps, and as phones are becoming smarter than ever, SMS remains the only way to reach ANY mobile phone user, anywhere, without having to know what type of mobile phone they have.

The ubiquity of SMS makes it an integral element of any effective communication for businesses in many sectors, and if it isn't yet, then it should be, because their target audience is now 100% mobile.

A powerful and meaningful platform to reach your target audience, anywhere, anytime, and on any mobile phone (regardless of type, brand or operating sytem):

  • Keep in touch with existing customers through branded content, alerts, reminders, confirmations, or coupons
  • Acquire new customers, and grow your customer database.
  • Drive sales through promotions and special offers
  • Receive feedback
  • Inform about changes or updates on your products and services
  • Optimize your process of registration, booking or validation

Database Cleaning & Mobile Number Validation in Real-Time

our HLR Lookup (or Number Context) service helps you keep your mobile numbers database up to date.

Nowadays, mobile subscribers regularly change mobile network operator, either keeping their original number thanks to Mobile Number Portability (MNP) or choosing to change mobile number in order to get latest phone model or in response to special offers by network operator.

Check the validity of a list of mobile numbers with extended details about those numbers (e.g. operator identification and roaming information).

Our HLR Lookup service is tailored to meet the requirements of service providers, financial institutions, and call centers, in need for keeping a healthy contact number for their customers or prospects.

It also addresses the needs of Tier1 and Tier2 mobile network operators to provide high-speed access to complete MSISDN information, including HLR, home network details (e.g. MCC/MNC, country prefix and ported status), and visited network information (e.g. where the subscriber is roaming).

Depending on your type of business, you may have 3 distinct uses for our HLR Lookup service (or Number Context):

  • Database Cleansing
    Clean up your database of mobile numbers by getting rid of unused and inactive numbers, and cut unnecessary costs.
  • Portability
    Resolve number portability issues with real-time number portability lookups to optimise message and voice routing, and save money.
  • Roaming
    Mostly used by clients in the financial sector to get roaming information to optimise routing, reduce costs, prevent fraud, and more.
