FAQ: SMS gateway

What is an SMS gateway?

An SMS gateway is a platform that allows businesses to send and receive SMS messages to one or many recipients at the same time.

Instead of sending manual text messages from a mobile phone, an SMS gateway gives you access to advanced features such as segmentation, automation, reporting and integrations with other software systems. This allows you to send marketing campaigns, service notifications and automated SMS messages – quickly, securely and at scale.

How much does an SMS cost?

The price of an SMS gateway depends on several factors: how many messages you send, which countries you send to, and whether you use features such as virtual numbers or shortcodes.

Besides your monthly subscription to inMobile, you only pay for the SMS messages you actually send. You can try inMobile’s SMS system free for 14 days, including 50 SMS credits to test the channel before deciding if it is the right solution for your business.

Is SMS GDPR compliant?

Yes, SMS can be used fully in line with GDPR. You must have valid consent from recipients, and messages must be handled securely. At inMobile, we are ISAE 3000 audited and follow EU standards for data protection.

We also provide tools such as unsubscribe links and blacklists, so you always maintain full control of your recipient lists.

How fast is an SMS delivered?

At inMobile, your SMS messages are delivered within a few seconds of sending. Delivery time may vary slightly depending on network conditions and the country of the recipient, but with inMobile’s infrastructure you can expect very high delivery reliability and stability. This makes SMS ideal for time-sensitive notifications and large campaigns.

Can I send SMS internationally?

Yes. With inMobile’s SMS gateway, you can send SMS messages to recipients worldwide. We offer global reach and have direct connections to Nordic telecom networks, ensuring your messages are delivered instantly and securely.

How do you send an SMS campaign?

In inMobile, you create an SMS campaign by selecting a recipient list, writing your message, and choosing whether to send immediately or schedule it for later. You can import contacts, sync them via integrations or add them manually.

After sending, you get access to a report with delivery rates, click-through rates via link tracking and unsubscribes – helping you measure results and optimise future campaigns.

How many characters can one SMS contain?

A standard SMS can contain 160 characters, including spaces and line breaks. If you use special characters or emojis, the limit is 70 characters, because the message encoding changes from GSM-7 to UCS-2. If your message exceeds the limit, the system will automatically combine it into one message for the recipient.

You can therefore send long messages – but keeping them short often performs better and may also reduce costs. Both because it performs best and because the price follows the number of characters. Read more about SMS character limits.

Can I automate SMS messages?

Yes. With SMS automations, you can send text messages automatically when specific actions occur. This could be welcome messages to new customers, appointment reminders or abandoned cart notifications from your webshop. Automation saves time, ensures timely communication and helps you create more personal and effective interactions.

Why choose inMobile for SMS?

There are many SMS gateway providers, but with inMobile you get a platform with high delivery reliability, flexible features and a support team always ready to help. We work closely with businesses of all sizes – from startups to enterprise – and help you get the most out of SMS as a channel.
