Data-Only SIM Cards: Who Can Benefit from Them?

Data subscriptions differ from traditional phone plans as they don't include voice calls and can't be used for calling. However, these data-only plans are becoming increasingly popular for various needs. Below, you'll find the uses you can make of a Swiss data subscription.

Data Subscription for Trackers and IoT Devices

With the rise of home automation and the growth of internet-connected devices (IoT), the need for a data subscription that can enable internet connectivity has grown in parallel. Data subscriptions suitable for smart trackers or intelligent alarm systems do not require high connection speeds since they exchange minimal data with the network. However, it's useful to choose a subscription that relies on a mobile network with good coverage to avoid signal loss.


The best data subscriptions for sensors or trackers currently available are the Digital Republic Flat 0.4 package and the Sunrise We Connect Track subscription. Both cost 4 CHF per month and come with no contractual obligations.


To compare them effectively, you can head straight to the offers section by clicking on the following button.

Data Subscription for Smartwatches in Switzerland

Another type of device that has become increasingly popular in recent years is smartwatches and other wearable devices (Smart Wearables). These connected objects require a slightly higher connection speed, though not excessively high compared to smart trackers. However, they certainly require a higher data volume. Typically, these data subscriptions are purchased by parents for their children to stay in touch while they are away from home.

One thing to pay attention to is the possibility of purchasing a data subscription with an eSIM, as most smartwatches do not offer the option of inserting a physical SIM card.


The best data subscription for smartwatches that we can recommend is undoubtedly the We Connect Watch by Sunrise, which costs 7.50 CHF per month and comes with no contractual obligations or activation fees. It offers unlimited data in Switzerland and a data roaming package for when you are abroad.


Other data subscriptions may also be suitable for your needs, so we recommend comparing them immediately to find the one that best suits your requirements.

Mobile Internet Subscription: Data SIM card for On-the-Go or as an Alternative to Home Connections

It's not a new concept, but with the expansion of the Swiss 5G network, the speed achievable with a mobile internet connection is practically equivalent to what can be achieved with home Wi-Fi. For this reason, today we can consider some mobile internet data subscriptions as a valid alternative to a home internet plan.

By purchasing a Swiss data subscription, you will receive a SIM card that can be inserted directly into your tablet or laptop to stay connected wherever you are. Alternatively, you can insert it into a 5G or 4G router and use the hotspot signal on multiple devices, much like a fiber or DSL internet connection.


If this is your connectivity need, it's essential to pay attention to the terms and conditions applied by each internet service provider to avoid receiving penalties on your bill for improper use of your data subscription.


If you want to find the best data subscription in Switzerland, compare the offers and find the one that suits you on the comparison platform. Alternatively, if you're looking for a stable and cost-effective home connection, you can check out the offers in this category in the dedicated section.

Which Data Subscription Suits My Browsing Profile?

If you're looking for a data subscription for an IoT device, it's best to search for a data subscription that offers a high volume of included GB, and you don't need to focus on the maximum connection speed. However, if you're seeking a mobile data-only offer, the reasoning is slightly different and depends on the type of usage.

Below, you'll find some data usage profiles and our recommendations for the appropriate data subscription:

  • 1 GB per month: Suitable for those who will use their new data connection to read news online, check Facebook occasionally, and send a few text messages on WhatsApp.

  • 5 GB per month: Suitable for those who occasionally use YouTube, Spotify, Instagram, and TikTok and make a moderate number of WhatsApp calls.

  • 20 GB per month: Suitable for those who use HD video streaming applications in moderation and make video calls and share photos and videos on WhatsApp.

  • Unlimited data: Suitable for those who extensively use video streaming applications like Netflix, Disney, or Amazon Prime Video and all other apps on their smartphones.

Read our advice and then identify the best data plan for Switzerland, thanks to the comparison section prepared by our team of experts. To find the right plan, you'll need to consider not only the price but also other package features to determine if it suits your needs.

Among the information to analyze, make sure to consider the supporting network that ensures coverage, contractual constraints, activation costs, and the maximum guaranteed internet connection speed.


  • Choose the Plan and Sign the Contract

Once you've identified the right plan for your needs and budget, you can proceed to the activation phase. In this case, there's no point in porting your phone number since you won't be able to make calls. However, we recommend checking with your current provider for the cancellation process if you're switching from another data plan. If you're activating a new data-only SIM, you can proceed without further checks.


  • Activate the New Subscription

After processing your request, the new provider will inform you of the exact date of the tariff change and send the new SIM card in advance (in the case of a physical card). The SIM card comes with a new PIN, which you can change in the settings after inserting the card into your smartphone for the first time. It's essential to complete this step, even if the SIM is intended for a mobile Wi-Fi device, to avoid unexpected network issues. Once you receive confirmation of the contract activation, you can start using your new data plan and browse anywhere you go.

FAQ Switzerland Data Plans

Which devices require a data plan?

A data plan is typically necessary for devices such as smartphones, tablets, laptops, portable gaming devices, and any other device that requires an internet connection to function. Additionally, many smart devices, like watches or smart speakers, may require a data plan to fully utilize their connected features.

How much do mobile data plans cost in Switzerland?

It depends on your needs, whether you're looking for an unlimited data plan or not. For example, an unlimited mobile internet plan can be available for less than 20 Swiss francs per month.

How important is the connection speed for a data plan?

The importance of connection speed in a data plan depends on the intended use. For activities like web browsing, email, and messaging, a basic broadband connection may be sufficient. However, for high-definition video streaming, online gaming, or other activities that require high bandwidth, a high-speed connection is necessary for a better experience.

What happens if I run out of data before the end of the month?

If your data plan runs out of data before the end of the month, you usually have two options. You can purchase additional data packages to extend your internet connection, but this may incur additional costs. Alternatively, you may experience reduced connection speed (throttling) until the end of the billing cycle, which means your connection may become significantly slower.

Are there data plans for using the internet abroad?

Yes, many companies offer international data plans or roaming options that allow you to use the internet abroad. These plans can vary significantly depending on the provider and the countries included in the service. It's essential to check the associated costs and usage restrictions before traveling abroad to avoid excessive charges. Alternatively, you may consider purchasing a local SIM card in the country you are visiting for more cost-effective data rates.
