Normal walkie-talkies just transmit directly from one radio to another. The likely range that can be expected from walkie-talkies can vary from a few hundred metres to a couple of miles or more.
The range is drastically reduced when walkie-talkies are used within buildings, or in a town or city with densely-packed streets of big houses, office blocks and other buildings.
A radio that might have a range of 2 or 3 miles in open, fairly flat countryside may only work over 500m in city streets.
All brands of walkie-talkie have basically the same power output, and therefore approximately the same range. You won't find that one brand of radio has a range twice as good than another, because they are all subject to the same basic laws of physics.

We now sell and hire a totally new type of "radio" that contains a SIM card like a mobile phone, and that transmits its signal via the mobile phone data networks. These radios get around the point-to-point range limitation of conventional walkie-talkies, and can transmit over any distance at all, provided that both ends are positioned somewhere that has a mobile phone signal. They are best suited for events in towns and cities where there is good mobile network coverage, and where "normal" walkie-talkies range is badly affected by lots of big buildings between one radio and another.

VHF (136 - 174MHz) signals generally work best outdoors, giving a somewhat longer range for the same power output than UHF (400 - 470MHz).
However, VHF signals really do not work well when there are obstructions like buildings around.
For most users who want their radios to be "good all-rounders", UHF is the best choice.
But if you plan to use your radios only in open countryside (or at sea - maritime radio is VHF) then VHF is better for absolute range.
