Best solution is update your phone to anything above Iphone X (10). Iphone 11 and up have esim. It makes life so much easier when you are traveling. You just purchase an esim from your Apple store, and you get data. The data allow you to use Whats App, Facebook messenger, etc. If you want to access to a telephone#, get a VOIP phone like Fongo - it is a VOIP # - then you will have a telephone to use. It is free to call any canadian #. I f you want to call any international #, you just have to load it with world wide calling credit $ (- international calls with VOIP phone are usually 2-3 cents per minute). We used this when we went to Europe last year - used it in Ireland and Italy. For the esim - we used either Nomad or Airalo. It cost me $25 with Nomad for 10g of data in Europe - was allowed to "hotspot" it to my laptop or tablet or my wife's phone. Used the Fongo phone to call home for free, and used it call any of the international numbers at a rate of around 2-3 cents a minute.
