The best global SIM cards take the stress out of travel. They allow users to receive calls and messages for free instead of incurring costly roaming charges. They also reduce the cost of outgoing calls so people can reach out to their local contacts without worrying about their credit.
These SIM cards have local affiliates so there should be no problems getting a signal. Most of these networks are already 4G or LTE capable so the Internet speeds should be high enough for video streaming. The results may vary depending on the location.
These are compatible with any unlocked phone. If you are going to buy a dedicated handset for this, then be sure to get a dual SIM phone so you can use the global SIM as well as your regular SIM in case you need it. The other slot could also hold a microSD card.
