What are the Ways to Connect to the Internet without Activating Roaming?

There are 3 ways to stay connected with our contacts without the roaming option.

Rent a Pocket WiFi

You can rent a pocket wifi from the local telco of the destination country to stay connected via the internet during the course of your trip. However, these options come with a cost and sometimes are not always hassle-free. Allow me to share with you my experience.

For example, in order for you to rent a pocket WiFi in South Korea, you need to leave the details of your credit card to the shop where you rented the device. That particular store does not accept debit cards. So if do not have a credit card, you won’t be able to rent a pocket wifi.

Purchase a Prepaid SIM card

You can buy a prepaid SIM card for one-time use in your destination country. This is a costly way to stay connected with your contacts in the Philippines. More so, it is not value for money if you are not internet data-heavy for the duration of your trip.

If you only carry one smartphone then you need to change sim cards frequently which causes hassle every time. You also need to inform your contacts in the Philippines about your new overseas number during your travel.

Here is T-Mobile which costs around 110 USD for 1 month but we only use it for 14 days. t mobile sim card for tourist california usaHere is Optus Yes which costs around 29 AUD for 1-month use but was only used for 10 days during our Sydney Australia tour. optus yes sim card for tourist australia Here is the pocket wifi I rented which cost me 15,000 Korean Won (15 USD) during our 5-day trip to South Korea. south korea pocket wifi rental price

Connect to WiFi Hotspots of the Hotel

Most of the time, you can use wifi hotspots of the hotel where you are staying. It’s free and probably high-speed, especially in South Korea. The problem with this option is you can only access the internet when you are already in the hotel.
