A Bolt has Wi-Fi and Bluetooth and no cellular radio. That is a decision rather than a saving, and it is worth explaining because a laptop that works in a data center is exactly the sort of machine you would expect to have one.
A cellular radio has to be certified by every carrier and in every country it might connect to, which is a year of work and a bill per network before anybody can use it. It is also the part that gets a device restricted: transmitters are what the rules are written about at blasting sites, on aircraft, in hospitals and in secure facilities, and a laptop carrying one is a laptop somebody has to think about before you can bring it in.
Leaving it out keeps a Bolt in the ordinary category. It is a computer with Wi-Fi, which is something every one of those places already has a rule for, and the rule is usually to switch the Wi-Fi off rather than to leave the machine at the door.
If you need to be online away from Wi-Fi, use your phone's hotspot. You are already paying for that data, the phone is already certified on that network in that country, and it does not put a second cellular contract on your laptop.
Being precise: Bolt still has Wi-Fi and Bluetooth, and those are transmitters. Somewhere that bans all radio still means yours. What leaving out the cellular radio does is keep Bolt in the same category as every other laptop, rather than making it the one that needs a separate conversation.
