Data only SIM cards are ideal for iPads, tablets, and mobile hotspots. You'll find the best-value SIM cards with MVNOs.

Tello offers affordable, data-only SIM cards, giving you full control over your plan without unnecessary extras.

With customizable data options, you can choose exactly how much data you need, whether for light browsing, remote work, or streaming.

Every plan includes mobile hotspot with the unlimited plan capped at 5GB, and while multi-line discounts aren't available, Tello's pricing keeps additional lines affordable.

Switching is quick and easy-activate your plan instantly with eSIM, or have a SIM card shipped to your door.

I also looked into Boost Mobile, Metro by T-Mobile, and Ultra Mobile. Metro requires in-store activation and charges higher prices. Ultra Mobile has strong international calling perks, but its data plans are more expensive. Boost Mobile offers good pricing, though data-only plan options are more limited.

For budget-friendly, flexible data plans with no surprises, Tello is a top pick.

• Build-your-own plan – Choose the right amount of talk, text, and data for your needs and avoid overpaying for unnecessary extras.
• Affordable, reliable service – Stay connected with high-speed data on T-Mobile's trusted 5G & 4G LTE network.
• Effortless activation – Order online and set up your service in minutes.

How to choose the best data SIM card plan

1. Network coverage: Low-cost carriers operate on the same 5G & 4G LTE networks as major carriers. T-Mobile boasts the fastest 5G speeds, according to this Opensignal 5G experience report 2023. If there's a particular network you prefer, choose an MVNO that operates on that network. Use our coverage checker to find the best carrier coverage in your area.
2. Data allowance: Do you really need an unlimited data plan? The big wireless companies want you to believe so, but in reality, the average monthly cellular data consumption is around 10GB. However, if you spend most of your time at home or work on Wi-Fi, it's likely you won't use a lot of data for things like video streaming, and your usage will be much lower. You can choose a data plan tailored to your needs with cheap cell phone providers, meaning you can pay less if you use less data.
3. Hotspot data: Most carriers allow mobile hotspot use but have a data cap on the amount of data that can be used via tethering. The limit depends on the carrier and plan you choose. Some carriers offer specific mobile hotspot plans.
4. Price: While big wireless unlimited plans cost around $75-90 per month, MVNOs offer the best prepaid data plans, ranging from $5-35 per month without sacrificing wireless coverage and data speeds. Watch out for hidden fees & taxes; some carriers include these in the price, whereas the major providers, such as Verizon and AT&T, don't.
5. Number of lines: With big wireless, you only get the advertised price if you buy 4 lines. With MVNOs, the price you see is the price you pay, even for one line. Many low-cost carriers now offer additional discounts for multi-line plans.
6. Bring your own device or buy new: While the big three love keeping their customers locked into a constant device upgrade cycle, MVNOs encourage you to bring your own device. This means you take back control and only change your device when it suits you.
7. Deals & promotions: Big wireless promotions can seem good at a glance. But once you read the fine print, it often leads to buying things you don't need and committing to 3-year contracts. Many MVNOs offer short-term introductory discounts for new customers, and their pricing is much more transparent.
8. Perks & add-ons: Most big wireless plans include "free" TV subscriptions; however, these usually turn into a paid subscription that is automatically added to your bill a few months down the line. A few low-cost carriers, such as US Mobile, do offer plan options with free subscription services, but we generally recommend keeping these subscriptions separate so you don't end up paying for things you don't need.
9. No contracts: Low-cost carriers have no contracts, offering more flexibility. However, some, like Mint Mobile, require you to sign up for a 3-month plan minimum, but their cheap data plans still offer better value for money than the big 3 wireless carriers.

Data SIM cards for international travelers

In the quest for affordable and flexible communication, especially when traveling, prepaid SIM cards have become a pivotal part of helping to stay connected. For travelers jetting from the USA to Europe and other various countries, the GSM technology underlying most prepaid SIM cards ensures phone compatibility, catering to both iPhone, Android, and other smartphones.

Whether you're looking to buy a new SIM card on arrival or opt for a travel SIM card, either is a great option. Also, if your phone is compatible, an eSIM can make this process even easier.

However, your current carrier may offer international plans, but they usually come with a hefty price tag. The best option can be getting a local SIM card, which presents a cost-effective option, often providing a substantial GB of data, free mobile hotspot data, and local call minutes, which are invaluable for internet access to navigate via Google Maps or stay connected through WhatsApp and Skype.

A new SIM card can offer an ideal plan tailored for each destination and guarantee the best rates.

How I choose the best carriers and plans

To select the best carriers and plans, I evaluated over 30 different carriers.

I rate carriers in five categories, with a star rating from 1-5, with 5 stars being the best. I then calculate the overall star rating using the five categories:

1. Value for money: I compare carriers based on price, features, benefits, and promotions. It's not just about the lowest price but getting the most bang for your buck.
2. Coverage: I look at network 5G and 4G LTE coverage across the US. I use coverage maps to determine service availability and data speeds in urban, suburban, and rural locations.
3. Customer experience: I take into account items such as current user experience, website and app usability, ease of switching, and customer service in terms of availability, channels, and satisfaction ratings.
4. Transparency: I assess whether carrier pricing is clear and straightforward. I examine the fine print to check for hidden fees, confusing terms or conditions, and misleading offers to ensure upfront, honest prices and advertising.
5. Range of choice: I evaluate the diversity of plan options to determine if they fit the individual needs of all customers.
