Choosing The Right SIM

With so many network providers out there offering a wealth of tariffs to choose from, it can be tough to know which is the right SIM card for your intercom system. Most SIM cards are designed for use within mobile phones and not static machines, so choosing the right one is crucial. It’s hard to know what to look for when selecting your SIM card, so here are our top tips on what to look out for.

Choosing the best network –

Selecting a SIM card on the best network in the area is key. We always recommend that you use a signal analyser to get an accurate signal reading wherever the antenna for the intercom is going to be mounted.

Contract or PAYG? –

Choosing a contract SIM, whether this is a 12-month contract or 1 month rolling contract, is usually a simpler and more cost-effective way to go. Contract SIMs mean that you don’t have to worry about topping up, ensuring your intercom connection is never interrupted.

SMS & MMS Marketing –

It’s important to remember that most SIM cards designed to go in a mobile phone will usually receive marketing messages from the network. Sometimes these are just text messages and sometimes these are picture messages. These messages can cause your intercom to behave in an abnormal way, so we strongly recommend contacting the network provider directly to ensure that these can be switched off.

Where is your intercom located? –

Most of the intercoms we manufacture are installed externally. If this is the case, you will need to choose a SIM which is designed for external equipment. Most SIM cards are not designed for outdoor environments and may fail over a long period of time.

2G, 3G or 4G? –

The Telguard & Optimus 4G LTE intercoms are backwards compatible, so work with 2G & 3G as well as 4G. However, we always recommend that the SIM is 4G to ensure that you get the best possible connection. This will drastically reduce downtime and improve the audio quality.

To make things super easy for our customers, TG Telecom have specially designed a SIM card to work with the Telguard and Optimus intercom systems.

What makes our SIM card so special?

Our enhanced 4G IoT SIM is designed to withstand corrosion, vibration, shock and extreme temperatures (-40°C to 105°C). This means they can be used in external environments and have a longer lifespan of up to 17 years. This is useful for all installations in long-term projects and particularly important in hard-to-reach locations.

IoT SIMs are also designed to be used in machines which means that the connection will automatically refresh to avoid interruptions. Standard SIM cards aren’t meant to be kept in static locations and are constantly looking for new cell towers in order to refresh.

Anti-lockout means that you can rest assured that our SIM cards will not send any SPAM messages. SPAM or marketing SMS & MMS messages can often cause the intercom to go offline or interrupt the service.

With our contract SIMs, you don’t need to worry about topping up, and you won’t ‘lose’ credit at the end of the month if you haven’t used all of your allocated minutes or texts. It also means that if your intercom doesn’t make an outbound call for a while, the SIM won’t be deactivated. Unfortunately, lots of PAYG SIMs are deactivated if they’re not used for a certain amount of time.

Finally, our activation process is quick and easy. Simply fill out our online form and our Network Ninjas will do the rest.
