Featurs of Cloud Mobile

Why choose Gamma as your Cloud Mobile partner?

Mobile numbers choice

We can provide your business with virtual long numbers or we can host your own range of mobile numbers. These can be used in OTT applications for voice and SMS traffic, as well as in A2P service for high volume transmission – allowing users to respond with either SMS or voice.

SMPP connection

We will provide the capability for you to deliver SMS to both UK and international numbers via an IPsec VPN connected to our SMSC, using the SMPP protocol. This is our preferred connectivity method and is fully supported by our operational teams.

Messaging receipting

With delivery receipting down to handset level (if required), you can provide evidence of receipt to your customers, allowing you to identify the success of marketing campaigns and helping your customer service teams.

Sender ID

Our service supports Alpha Numeric (OAS) tags on Mobile Terminating messages, enabling you to provide customers with easy to recognise sender ID names for your messaging.

Brands that trust Gamma.

I can highly recommend Gamma as a very good, trustworthy, reliable partner in a quite turbulent market. Gamma do what they say, when they say and provide a service that works well. I would seriously recommend Gamma as a potential partner.
