How to use a pocket 3G Wi-Fi router in Ukraine?

Question

Computer networks

You need to feed the phone and laptop with the Internet.
Let's divide this question into sub-questions:
1) What device to buy? Optimal in terms of price / performance, is it possible to take something from dx.com? As I understand it, it is better if it is a box with a battery, wi-fi and a SIM card slot.
2) What card is better to insert there? I would not refuse unlimited speed from a megabit. I don’t need to watch movies online, but I need comfortable work with websites and transferring a couple of files via FTP.
I would be glad if you said something like:
"I use MTS 3G, I pay 90 UAH per month, 2 megabits, the limit is 10 gigabytes per month, I'm satisfied
" communication in the toilet

Answer 1

1) I use Iphone
2) I use 3mob, I pay 180 UAH per month, 25GB/month, I'm happy with everything

Answer 2

A friend uses an intertelecom Huawei EC 5321u-1 (to make it clear the Wi-Fi ad is a dog, I don’t know if I can throw links)
He stands at home as a stationary (due to the inability to conduct wired Internet) + carries with him.
I won’t say for the price, etc., but I know that the comrade is happy as a beetle.
They often came to visit and 3-4 people hang on a waffle with web surfing without any problems. Alone, you can watch videos from Youtuba, VK.
