Public Mobile only works in Canada and the United States (with the purchase of roaming add on). You can not use your Public Mobile in any other country. If you wish to use cellular services while you’re in another country, you can look at https://www.airalo.com/ for affordable data plans and then download an app like Fongo and pick a local number to where you currently live. They do however charge for texting. TextNow is free calling and texting. You can use both of these VOIP programs via WiFi or on a data only SIM card.
if you'll have wifi during your travels...consider downloading the free TextNow app. Using wifi or separately purchased data, you'll be able to send / rec free calls and texts to most any US or Cdn number. Did I mention it's free !
