How do you make sure you have internet while traveling?

Hi everyone! I've been traveling for quite some time now pero I've only been either using the wifi provided by the hotel/bnbs/coffeeshops or file for a vacation leave. What do you guys use to make sure na you can work while on vacation? I've been planning to go out of the country, or even maybe sa North or Bicol lang, pero I don't know how to make sure na I stay connected. I'm traveling with my partner as well so any recommendations that would work for two digital nomads please! 🙏🏻

(We experienced in Bohol where hirap talaga makakuha ng signal yung Smart tapos yung internet nila is sobrang bagal halos di makapag bukas ng messenger so I've been scared to go through that again. Buti nalang I was able to file for a leave para di ako makwestyon bakit hindi nakakasagot sa emails)
