Welke SIM-kaart werkt het beste voor GSM-poortopeners?

Welk SIM-formaat heeft elke module nodig?

Different gate opener modules use different SIM card sizes. Using the wrong size means the card won't physically fit.

If your carrier only issued a micro or nano SIM, use a plastic adapter (under EUR 1) to convert it to standard size. Make sure the SIM sits flush and the gold contacts align with the reader. Alternatively, request a multi-format punch-out SIM card from your carrier and use the outermost frame.

Prepaid of abonnement: wat is beter?

For a gate opener, a prepaid SIM is almost always the better choice. Gate openers use almost no airtime. A phone call to open the gate is free (the module rejects the call after one ring). The only costs are the occasional SMS command and keeping the SIM active.

Contract SIMs work but are overkill. You pay monthly for data, calls, and SMS you'll never use. The only advantage is guaranteed activity (no expiration risk).

SIM PIN-vergrendeling verwijderen

According to the RTU5024 and Callny user manuals, these modules require the SIM PIN to be disabled before insertion. The modules cannot handle PIN prompts at startup.

1. 1.Insert the SIM into a regular smartphone.
2. 2.Go to Settings, then Security, then SIM card lock.
3. 3.Disable "Lock SIM card" or "SIM PIN."
4. 4.Enter the current PIN (printed on the SIM card's packaging, or often 0000 or 1234).
5. 5.Remove the SIM and insert it into your gate opener module.

If you entered the wrong PIN three times, the SIM is locked and requires a PUK code from your carrier. After 10 incorrect PUK attempts, the SIM is permanently locked.

2G-netwerk uitschakeling: ondersteunt je provider het nog?

This is the most important factor for gate opener owners in 2026. Multiple carriers worldwide have shut down their 2G (GSM) networks, and more shutdowns are scheduled through 2028.

Countries where 2G is shut down

• US:AT&T (2022), T-Mobile (2024). Use 4G modules only.
• Australia:All carriers shut down 2G by 2018.
• Japan/Korea:No 2G service available.

Countries where 2G is still active (2026)

• UK:EE, Vodafone, Three, O2. Shutdowns planned 2028-2030.
• NL:KPN, T-Mobile. VodafoneZiggo shut down 2G in 2025.
• DE:Telekom, Vodafone, O2. No firm shutdown dates.
• FR:All major carriers. Orange plans 2G shutdown by 2028.
• ES/TR/RU:All carriers still operate 2G.

If your carrier has shut down 2G, you need the 4G LTE variant of your gate opener module. The hardware compatibility page lists available variants for each module.

Speciale IoT SIM-kaarten: de moeite waard?

Companies like Things Mobile, GateSIM.ie, and AnywhereSIM sell SIMs specifically for gate openers. They offer no inactivity expiration and multi-network roaming, but cost EUR 2-5/month compared to EUR 5-10/year for a regular prepaid SIM.

For most gate opener owners, a regular prepaid SIM is the right choice. IoT SIMs make sense only for remote locations with weak signal or if you manage multiple openers across different countries.

SIM-kaart setup checklist

1. 1.Insert the SIM into a regular phone first
2. 2.Disable the SIM PIN lock
3. 3.Verify voice and SMS work (test call + test SMS)
4. 4.Note down the SIM's phone number
5. 5.Check that your carrier still operates a 2G network (for 2G modules)
6. 6.Top up credit if prepaid
7. 7.Remove the SIM and insert into the module

For the full setup process after SIM insertion, see the RTU5024 Setup Guide.
