What is an international travel SIM card?

A travel SIM card with unlimited data helps you connect and use internet services in several countries. These are categorized into specific areas, continents, or regions.

They work thanks to contract agreements with local operators in each country. You will connect to their networks as long as you are within their coverage area and have an international SIM card with good service.

An international travel SIM card does not work with a nonestablished provider. If you connect with the incorrect provider, you must select the right network manually on your phone’s settings. Do not worry. Our recommendation is the international virtual SIM card that Holafly has for more than 170 destinations worldwide, which we will discuss in a later section.

International SIM Card and International Virtual SIM Card: Are they the same?

There is a clear difference between these two, which is the international virtual SIM card, also known as eSIM, with the technological evolution of the traditional international SIM card.  The main novelty is that eSIM cards do not require a physical installation in your phone, so you can have unlimited data anywhere in the world in a few minutes.

How do I know if my cellphone is compatible with a virtual SIM card?

This is important before buying your international virtual SIM card because not all cellphones are compatible with this technology. As they are a recent development, the industry is still in the process of moving to this type of chip. To help you check if your smartphone is eSIM compatible, you can take a look at Holafly’s updated list.

Of course, as with physical international SIM cards, your phone must be unlocked for international use. Some providers sell cellular devices with regional or carrier restrictions, so you should confirm if this is the case for your phone.

Virtual SIM vs. physical SIM cards

The first virtual SIM cards were indeed seen on the market a few years ago in very few cellphones. However, in the last couple of years, their implementation has expanded. Today they represent the next step in telecommunications due to their accessibility and speed of delivery anywhere in the world.

International virtual SIM cards are one step ahead of their physical analogs, and it is only a matter of time before they are standardized in all phones. On Holafly’s articles of interest find more information on eSIMs so you can learn more about them and compare them to the physical alternatives.

Where to get a travel SIM Card with unlimited data?

Advantages of a virtual SIM card for traveling abroad

If you want even more reasons to buy an international virtual SIM card for your next trip, here are some of its advantages:

1. Internet without complications or contracts

For all tourists looking to get an internet connection abroad with easy access, international eSIM cards allow you to do so without signing contracts. Local SIM card providers will generally ask you for personal information as well as go through national registration processes.

2. Clear your mind and don’t think about how much you are spending.

The prepaid virtual SIM card allows you to make a single payment for your service and, in the case of Holafly, offers unlimited data for many services. No more high roaming bills or running out of data in the middle of your trip.

3. Multi-country eSIM

As we already mentioned, with Holafly’s travel virtual SIM cards, you have access to regional options that allow you to maintain coverage in several countries. If your trip to Europe or North America takes you to more than one destination, these eSIMs are your ideal solution.

4. Online recharge option

This is also known as top-up; with this service, Holalfy will email you when your plan is about to run out. In this email, you will find a link to buy an extension of your plan and continue enjoying your virtual SIM card with peace of mind.

5. You keep your WhatsApp number

You don’t have to worry about your friends and family not being able to contact you. With Holalfy eSIMs, you can keep your local SIM card and your WhatsApp number at the same time.

Disadvantages of a SIM card for travel abroad

Despite having many advantages, international virtual SIM cards do not escape from having some disadvantages. You will find some differences regarding their physical analogs that you might need on your trip. 

Generally, it happens that when you buy a travel SIM card with unlimited data in an online store, it does not include a local number, so you will not be able to make analog calls or send SMS. What you will be able to do is use instant messaging apps with unlimited data, such as WhatsApp, Telegram, and Skype. 

With this in mind, virtual SIM cards are still the top recommendation for those tourists who want a fast, secure, and hassle-free way to stay connected while traveling.

Avoid roaming charges with international SIM cards

For many years, it has been common knowledge that roaming services are quite expensive regardless of your carrier. 

When no other alternatives were, roaming was the solution for many who wanted to be connected abroad. Today, if you buy an international SIM card, you can avoid paying this high cost and still have the same goal of maintaining an internet connection while traveling. To find out the availability of your operator to roam in any destination, keep in mind that they usually classify it by zones. 

The farther away the destination country is from your country of origin, the more expensive the service is. The European Union is a particular case of this situation, so many operators allow you to continue using your minutes, messages, and data within member countries. However, you should check with your provider because, in numerous instances, they may apply flat rates. 

Beyond this small exception, keep in mind that for all other destinations, the price to pay will always be considerable compared to the virtual SIM card alternative. Don’t stay behind the times with the old-fashioned and expensive roaming; buy a travel SIM card with unlimited data for your next trip whenever you have the opportunity.

Roaming rates

Considering English-speaking operators such as Three, Verizon, Rogers, and AT&T, we can consider daily rates from $5 to $15 to have internet. It is also possible to find rates above this, but it is less common.

Something similar happens with calls or messages abroad, so if we also want to use these services are additional daily rates of $5 or more. As mentioned above, the cost is higher in more distant areas and can go up to $6 per minute per call when calling from these destinations. Note that this applies whether you make or receive calls.

Not surprisingly, the reputation of the expensive roaming service comes to the fore. For this reason, with a virtual SIM card that you can buy and receive immediately anywhere in the world, you will solve your internet connection abroad in the best way.

International SIM card vs Roaming 

Here is a quick comparison between virtual SIM cards, physical data SIM cards, and roaming services. From a general point of view, these three alternatives are intended to keep you connected abroad only with your phone and chip. You will be able to see which one best suits your needs.

Table 1. Comparison of virtual SIM cards, International prepaid SIM cards vs. roaming services

As we can see, the three alternatives fulfill their objective of having internet abroad. But if we look closely, the virtual SIM card is the only option that allows you to get unlimited data at a good price and with excellent coverage.

Even so, each option has its usefulness, and in case you prefer one or the other, you will always be able to stay connected to the internet. For those of you who need to receive SMS or consume talk time abroad, your most useful option will be the roaming service of your local operator. 

On the other hand, if you are an average traveler who wants to keep an internet connection for a low cost and without many steps to achieve it, surely your ideal option will be the travel eSIM. Also, with unlimited data options like the ones offered by Holafly, you will always be able to navigate to order an Uber, look up an address on Google Maps, or do whatever you need.

International data SIM card vs. Pocket WiFi

Pocket WiFi is another option to connect to the internet during your travels. It allows you to share data between multiple devices, and, most importantly: it’s unlimited!

But make sure to read the terms or conditions and the fine print regarding restrictions. Sometimes, there are restrictions even if providers claim to offer the longed-for unlimited internet feature.

Look closely at the daily limit they offer. It is usually around half a gigabyte or 1 GB. If you start watching a Netflix movie or series, you’ll be halfway through the movie and then left in the middle of the road without internet.

One limitation of Pocket WiFi is the number of devices you can connect to the internet. If you’re traveling in a group, it’s possible someone may be left without a connection.

Be aware of these limits when using Pocket WiFi. Firstly, battery life will be extremely low  (you can rent a new battery for around $10). Also, remember to review the conditions in case of loss or theft, The price of the penalty can be $150 with immediate effect.

Sometimes pocket WiFi sellers don’t mention the shipping fee, which could be between $8-10. You may also have to pay to return the device once your rental period is over.

Comparative table

Now that we know better how pocket WiFi works, let’s see a quick comparison with international SIM cards.

Table 2. Comparison between international virtual SIM card vs. international data SIM card

After looking at the table, we can conclude that it seems that pocket WiFi is becoming obsolete. In previous years, they were a viable option to connect to the Internet abroad. Today, smartphones have evolved by leaps and bounds and are replacing them.

With some of your international data SIM cards, you can also share data with other devices, and you don’t have to rent anything. Nor do you need to receive or return anything that is not yours. In short, you are worry-free.

Conclusions on Virtual SIM cards for international use

International virtual SIM cards are an excellent alternative for you to avoid paying roaming fees and have Internet on your travels.
