I read on Google that the mobile and Wi-Fi there is completely terrible, or it just seems to me that it's not fast at all. Is there any point in buying a SIM card? How much does mobile internet usually cost? If you use Wi-Fi in some 2-star hotel, can you at least use WhatsApp/Telegram?
About $10 for a card at the airport, take it and use it for a month. The Wi-Fi may be weak at the hotel
Dialog worked well in the center of the island and on the coast
I always use a Dialog SIM card, 4G is almost everywhere, sometimes it's faster, sometimes it lags a bit, but it's not critical. We watched movies on the laptop without any issues, video calls were fine too.
Thank you for the helpful review.
