SMSBOX — Belgian SMS gateway for education

SMS for schools — reaching parents when it matters

A school email gets read — sometimes. A text message gets read, usually within minutes. For most of your communication, email is perfectly adequate, but for the urgent part — a closure, a lockdown, a bus stuck in traffic — you need a channel that is certain to arrive.

SMS also has a practical advantage that is often overlooked: it works without an app, without a parent portal and without parents having to install or remember anything. Every mobile number in your student records is immediately usable.

SMS for schools via SMSBOX

Where does it go wrong today?

Emails that go unread

What has to arrive today cannot wait until someone happens to open their inbox.

Phone rounds during an incident

Calling hundreds of parents is not an option at the moment it matters.

Parents without the parent portal

Not every family installs the app or logs in to the platform. A mobile number is something everyone has.

This is what it looks like in practice

The examples below are illustrations. The parts between percentage signs are tags: you fill them in from an Excel list or through the API, so that every recipient gets their own version.

Closure

The school stays closed today due to a power outage. No childcare is provided.

School trip

The trip's bus is stuck in traffic and will arrive about 45 min late. No need to wait.

Absence

%firstname% was not reported absent today and is not at school. Please contact the school office.

Parent meeting

Reminder: parent meeting on %date% at %time%, room %room%. Reply YES to confirm.

Staff call-up

Urgent: substitute needed for tomorrow morning. Available? Reply YES.

How does a school set up SMS communication?

1

Create your groups

Divide the numbers into groups per class, grade or role — parents, staff, substitutes — in the online phone book.

2

Prepare standard texts

Write the messages for a closure, an incident and a call-up in advance, so you have nothing left to draft during an event.

3

Decide who can send

Give management and the school office each their own subaccount, so communication does not stall when one person is absent.

Good to know

Work with correct, up-to-date numbers: a list that has been in use for years inevitably contains changed numbers. An annual check and a test message at the start of the school year keep your reach reliable.

At SMSBOX you pay per message sent, from €0.06 per SMS to Belgium (excl. VAT). No subscription, no setup costs: a month without any sending costs you nothing. All processing takes place on Belgian servers, within the GDPR.

Frequently asked questions about SMS for schools

No, it complements them. Use the portal for everything that can wait and must remain consultable, and SMS for the urgent part that has to arrive today. The advantage of SMS is that nothing needs to be installed: every mobile number in your administration works immediately.
Via an Excel import from your pupil administration. You save them as groups — per class, per year, or one group with all parents — so you only send a message to those it concerns.
For school-related announcements about their own child, that is operational communication, not advertising. Do state in your school regulations or privacy statement that you may contact parents by SMS, and keep the number list up to date.
Yes, and that is exactly the reason to have it. An SMS needs no internet connection, no app and no working school infrastructure. If you send from a mobile phone or from a computer outside the school, you reach all parents even when the school network is down.
Yes, if you send from a virtual number or our shortcode. Useful for confirming attendance for a parents' evening or a school trip. If you do not want replies, you can also keep it one-way.
You pay per message sent, from €0.06 per SMS to Belgium (excl. VAT) at high volumes. There is no subscription and no standby fee: a school that uses it only for emergencies pays almost nothing in a quiet year.
Yes, via sub-accounts. That way communication does not depend on one person with one password, and you can see who sent what.
