If you are going to travel internationally a significant amount, my recommendation is to get the Tmobile plan which gives you free text and 3G data. The plans are more expensive on a per month basis - I pay $60/month - but you have zero ($0) cost to automatically get the above when traveling everywhere that I have been: Europe, Asia, Central and South America, Japan, Russia. Canada and Mexico both work fine too.
There is a $0.20/min fee for receiving or initiating voice phone calls. This is fine since you have full control over either plus can avoid if you WiFi call (see below).
I've been a Tmobile customer ever since they merged with Sprint, but I think the modern version of the plan is called Magenta. It also includes a Netflix basic subscription, WiFi calling, free in flight internet/texting on a number of airlines including United.
Tmobile also allows iPhones at least to be used as hotspots for laptop based email.
I see there are 55+ versions of Magenta, so may be even cheaper than what I am paying now although my actual plan is a legacy one equivalent to Magenta+.
If you want/need greater bandwidth than 3G, you can either get the higher bandwidth options (4G, 5G) permanently or pay for passes to temporarily increase bandwidth. A 10 day pass is $35.
With this plan, there is no need for juggling phone numbers for people to contact you, or to recharge a sim, or to get a sim (which is increasingly more difficult in the West).
And finally: you don't have to worry about Google spying on you, either. I will never use a Google service: basic Android, gmail, Chrome, or even search if I can help it.
