Thanks for starting this John!
Another tip when it comes to data roaming is eSIM. If you have a phone with a built-in eSIM (e.g., iPhone XR, XS and 11), you can buy a few gigabytes of data for a very reasonable price and use it all over Europe. The best part? You can do everything online, and you don't need to receive a SIM (you're just reprogramming your built-in eSIM).

Keep in mind that countries like Germany often make it hard for your as a foreigner to buy a sim card, especially at stores like Vodafone and Telekom. You'll need to go to more "immigrant friendly" sub-providers like Lebera mobile. Your mileage may vary.Staying communicated with family and friends is important. You can take your mobile phone with you, yet never use your Lebanese SIM in a foreign country. For the EU specifically, you can buy any SIM card (e.g. Vodafone) that gets you an internet connection (which is relatively cheap). The sim will work at no extra cost in any EU country you are visiting according to their roaming policy.
