On the third day, we looked for a SIM card because we did not buy one on the second day. At noon, we left the accommodation together and went to Viettel, a mobile network company in Vietnam. It is similar to Telkomsel in Indonesia.
Across the street from the Viettel store, there was a Domino's Pizza with a buy one, get one free promotion. We decided to share the cost and buy some pizza. We ate the pizza while waiting for our supervisor to buy the SIM cards.
After we finished eating, it started to rain. We waited in front of a convenience store until the rain stopped. When the rain was over, we walked back to our accommodation.
We arrived at the accommodation at around 4:00 p.m. After Maghrib prayer, we had a Qur'an study session (halaqah) together. After Isha prayer, we had dinner. The menu was Indomie with rice. Indomie is not only popular in Indonesia but also in Vietnam. We even found some flavors that are rare in Indonesia, such as the Grilled Ribs flavor.
