NO! Changes to the Wireless network do not affect alarm system SIM Cards? We keep updating the network security to keep your alarm system online.

Alarm SIM powered by SpeedTalk currently does not offer any roaming (domestic or international), therefore you will be unable to use your smartphone if you are off the network or outside of the United States. We are dedicated to delivering the greatest coverage for our clients. Every day, we work hard with our carrier partners to increase service across the United States.

You can only receive a SIM card from Speedtalk if you buy a plan from us, and we only supply SIM cards via the GSM-T network. Check our GSM-T coverage map to ensure that there is coverage in the areas where you will be using your phone or device frequently. In addition, our IoT plans such as Alarm System, Smartwatch, and GPS Trackers operate on the GSM-T network.

A SIM card is an integrated circuit intended to securely store the international mobile subscriber identity number and its related key, which are used to identify and authenticate subscribers on mobile telephony devices

a SIM (Subscriber Identity Module) card is a tiny, portable memory chip that stores information about you as a cell phone user. On it, there’s a seventeen-digit code that designates its country code of origin, the system carrier (such as AT&T or Verizon), and a unique user ID.

You may wonder, “Who cares about this code?” A valid question and guess what: phone carriers do. It’s how they attribute cell phone bills and charge us.

Above all else, SIM cards are super handy because they can be easily transferred from one device to another. Just like in my opening story, all that you’d need to do is take it out of one phone and slip it into the new one. By making the switch, most (if not all) of your contacts and personal settings will transfer with it, making life all the easier.

SIM cards were introduced all the way back in 1991. The first SIM card was about the size of a credit card. Since then, there have been several updates and iterations, making them smaller and smaller.

This evolution closely aligns with the history of the GSM (Global System of Mobile Communications) mobile network. Developed to describe protocols for second generation (2G) (3G) (4G) AND (5G) cellular networks, the GSM today stands as the default global standard for mobile communications.

SIM cards are a crucial part of GSM networks, storing user information required for authentication. Ultimately, this allows both your phone to connect with a GSM network and GSM networks to track your phone usage (specifically, your minutes, texts, data usage, etc), giving carriers the information to send you an accurate phone bill.

GSM is the standard network in America, Europe, Asia, Africa, and most other places. Interestingly, besides GSM, the United States has an additional network called CDMA (Code Division Multiple Access) that is used by carriers such as Verizon and Sprint. Phones on the GSM or CDMA network can use any carrier’s network, lowering the costs for the carriers and its users.

When it comes to your phone’s connection with either network, SIM cards are essentially the brain of your device.

A SIM Card is a chip that all devices carry. The chip that communicates with our network.

There are 3 three basic sizes of SIM card: the standard, the micro, nano.

Of th3 3 three, the Standard is the original SIM and the largest. Today, these are mainly used on older phones.

The Micro SIM card is essentially a standard SIM card with the extra plastic around the circuit board trimmed off.

A trimmed version of the Micro, the Nano is the smallest and used on today’s iPhones. Although minuscule compared to prior versions, the Nano still holds the same amount of data as earlier SIM cards.


When skimming the evolution of the SIM card, you likely noticed that they’ve become much smaller. But prior to the launch of the iPhone 4 in 2010, we really only had one SIM card size. Introduced in ‘96, it was the standard used in every phone and it made the GSM folks happy. Essentially, it was your entire phone on a card. It made things simple. If you wanted a new phone, all you’d need to do was take that SIM out, pop it into any phone and suddenly your phone number would be transferred to the new device. For over a decade, this was the standard, which made switching phones a breeze. Now? Not so much.


Enter Apple. Wanting to save precious room for its newest generation of smartphones, Apple switched from using the standard Mini-SIM to the Micro-SIM once the iPhone 4 hit shelves.

Surprisingly, the Micro-SIM wasn’t some new flashy SIM developed for the latest iPhone. Believe it or not, it was first introduced in 2003.

Back then, its purpose was clear: if a device was too small to fit a mini-SIM, you’d have to use the micro-SIM. In addition, the micro-SIM was designed for backward compatibility, meaning it can work with input generated by an older version of the SIM (such as the Mini-SIM).

In addition, despite its smaller size, the micro’s performance wasn’t impacted at all, as chip’s contact area remained the same. It turned out to be scaled down – the card only needed its excess plastic to be cut from it.

When Apple released the iPhone 4 with the micro-SIM, it became the standard for most smartphones. Samsung, Nokia, and HTC are just a few of the manufacturers that adopted the new Micro-SIM. During this time, several upgrading to the iPhone 4 opted to use an adapter to get their SIM cards cut down to Micro’s, as well. 


If you thought Apple was done using smaller SIM cards, think again. Perhaps Apple was peeved they had to use a SIM card from 2003 on the shiny new iPhone 4. Maybe they just wanted to stay ahead of the curve and throw competitors off their trail.

In any case, the launch of the iPhone 5 prompted the public to realize there was a new SIM in town: the Nano-SIM. This choice to go small made life pretty difficult for users. Anyone upgrading to an iPhone 5 or switching from Android now had to get a new SIM card or an adapter.

Fortunately, most smartphones released since 2014 (both iOS and Android) now support Nano SIM card technology as the standard. Still, it’s sad to see a card that small take over, as it was always much easier changing phones with the Standard SIM compared to the Nano.

As a product of the 1990’s, it’s amazing to consider the SIM card’s evolution, especially when compared to how fast other technologies of the era morphed and died out as newer solutions were innovated. As a link tying together the subscriber’s phone data with their network, the SIM card’s purpose has always been clear – but it will be interesting to watch what another two decades do for the future of this purpose and the SIM card itself.

Inserting or removing a SIM card is an easy process once you determine where it is stored on your phone. Depending on the type of phone, it could be placed behind the battery. In that case, you will have to open the back panel. For other phones, the SIM cards can be found on the side of the phone.

Removing the SIM card is simple if you have the right tool. Depending on what kind of phone you have, you can easily pop it out of the slot with a paperclip or the edge of something like a credit card. There are some SIM cards that are in easier spots that can slide out with the tip of your finger.

Is installing the SIM card hard?

Not at all, it takes about ten seconds. Take a look at this example of someone placing a SIM card in a phone.



If you are not sure how to insert the SIM card, look up your phone manufacturer’s instructions online or watch a video on how to easily replace the card in the right slot.


Yes, SpeedTalk will never deny you of service but your carrier has to unlock your phone for you to be able to use any other wireless provider. Please check with your current carrier to make sure you’re out of contract and the phone is in good standing.
