SMS or RCS

SMS or RCS – Which Service Suits You Best?

RCS takes messaging to the next level with advanced, interactive features compared to traditional SMS and MMS. It supports a richer user experience, allowing you to send longer texts, high-resolution images, videos, and interactive elements - bridging the gap between businesses and consumers.

Simply put: SMS is perfect for short, critical messages like alarms, reminders, verification codes, and alerts. RCS, on the other hand, is the ideal choice for interactive campaigns, multimedia content, and engaging customer dialogues

Network Lookup

Verify Subscriptions and Network Affiliation Effortlessly

When running large SMS campaigns, it can be difficult to know if all subscriptions are active. With Spirius Network Lookup, you can easily find out if a number has a subscriber and which network a specific subscription belongs to.

Network Lookup specifies the operator's network code (MCCMNC) or the Service Provider ID (SPID) from SNPAC (Sweden only). This is essential since many mobile numbers are ported, meaning you cannot identify the network based solely on the phone number prefix.

You access Network Lookup via the Spirius API.

Magic icon

Sweden gives the Service Provider Identity code (SPID) from the Swedish SNPAC register (Swedish Number Portability Administration Centre AB).

Chart icon

Basic provides the network code (MCCMNC) by HLR lookup and also gives you the status of the subscription.

Pie icon

Advanced provides both operator code (SPID), the network code (MCCMNC) and the status of the subscription.
