How to Activate Roaming for Smart, TNT, and SUN Subscribers

You may want to activate the roaming option on your Smart, TNT, or SUN powered smartphones if you are traveling out of the country. This post will show you the different possible ways to do it whether you are in the Philippines or already abroad.

Activating the roaming feature of respective telecoms powered smartphones is one of the concerns of both the first time and frequent travelers. The reason is basically the same, they want to stay connected with their loved ones, friends, and colleagues in the Philippines.

Needless to say, with the use of the internet, there are many ways to stay connected with our contacts without the roaming option.

You can rent a pocket WIFI, or purchase a sim card from local telco of the destination country to stay connected via the internet during the course of your trip. You can use all the online applications for messaging, and video calls.

However, these options come with a cost and sometimes are not always hassle-free. Allow me to share with you my experience.

For example, renting pocket wifi in South Korea. In order for you to rent pocket wifi, you need to leave the details of your credit card to the shop where you rented the device. For that particular store, they do not accept debit cards. So if for some reason you do not use CC ( because you are allergic to it like me) and only use a debit card, you won’t be able to rent a pocket wifi.

They will charge the credit card if you did not return the device after your rental duration has ended. At least according to the store attendant that I have talked to.

Purchasing a prepaid sim card for one-time use on your destination country is also not cheap just so you can stay connected with your contacts in the Philippines. More so, it is not value for money if you are not internet data-heavy on the duration of your trip.

If you only carry one smartphone then you need to change sim cards which can cause 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. Also, I only use it to connect using FB messenger, and different mobile map applications for directions. Because at night time at the hotel, we only use the in-house wifi. t mobile sim card for tourist california usaHere is Optus Yes which costs around 29 AUD for 1-month use but was only use it for 10 days during our Sydney Australia tour. I also only use it to connect with Facebook, and Map applications. 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 Most of the time, you can use wifi hotspots of the hotel where you are staying. Its free and probably high speed especially in South Korea.

To avoid hassle and unnecessary high internet data cost while on tour, you can instead choose to activate roaming on your smartphones running on Smart, SUN, or TNT SIMs.
