Alternatives similar to the international eSIM

As mentioned above, eSIM is a recent technology that solves Internet connection problems for travelers. Before this service arrived, there were and still are other options that you may be interested in knowing about, in case the eSIM does not meet your needs. Among them we have the following:

International roaming

It is perhaps the best-known service and you have it at hand in most cases, after getting a plan with your mobile operator. Some of them offer it for free (as is the case in the EU roaming) and sometimes there are special rates.

International roaming is usually expensive in most destinations. Paying for every MB used is the norm, and must be borne by each traveler leaving his or her country.

Although not everything is discouraging, if you have registered your mobile number you will be able to continue using this service when roaming. This way you will be able to receive SMS if you need to make payments abroad. Normally receiving text messages while roaming is free of charge. The important thing is to clarify this issue with your bank before you leave.

Travel SIM cards

This alternative is the one that most closely resembles your local SIM card. In most cases, they include a number and mainly mobile internet. There are prepaid travel eSIMs to use and dispose of, as well as subscription or contract eSIMs. The former is more convenient because they do not tie you down, nor do you have to sign or risk-taking on usage commitments.

However, you should keep in mind that travel SIM cards are dedicated to that. Nothing else. Normally, you cannot receive messages from the bank and in many cases, they do not include calls. Travel SIM cards are an excellent option for those who need to stay connected to the internet and use their social networks, upload photos to their networks and use Google Maps, among other uses.

Pocket WiFi for traveling

Being able to have a portable WiFi network always at hand is the dream of many, and the Pocket WiFi is the solution. With this device, you will be able to connect to the internet on your travels through a wireless network that makes use of mobile data from a SIM card.

Pocket WiFi along with international roaming are the most expensive options for connecting to the internet abroad. With the service, you have to keep in mind that you are paying not only for the use of mobile networks but also for the rental of the device, insurance, shipping, and return.
