Purchase and activation are easily handled online, with instant activation. This option works if you have a device with a secondary e-SIM compatible slot, which can be found on most modern smartphones.
International roaming
International roaming tends to be expensive and may come with speed limitations. It is generally only suitable for very short-term visits or emergency situations where immediate connectivity is crucial.
Pocket wifi rental
Renting pocket wifi devices is a viable option to share the cost of data when travelling in a group. However, they can be bulky, and add to the list of devices you need to worry about on your trip. Additionally, the group needs to stay together for everyone to have internet access, which can be inconvenient for some travelers.
