How to always have high-speed Internet with you?

Question

WiFi

I have an iPhone 5 and a MacBook Pro and have to beg for Wi-Fi. And especially now, in the summer, I would like to be able to do my business from anywhere in the city.
I thought about:
1) Put an operator in the iPhone that gives 3G. It turned out that ordinary GSM operators do not provide 3G, but there is some kind of muddy 3Mob, which I could not even find a technical support phone on the website to call and find out everything. Who used it, what will they say?
2) Take a USB 3G modem-"flash drive". It solves the problem of the Internet only for the MacBook, therefore it does not fit. + I do not want to constantly poke it into USB.
3) Take a portable router on a battery, which will take the Internet from the card of some operator and give it to me in the form of personal Wi-Fi. An interesting option. Stops some misunderstanding what I need to do. Select a device and select an operator and combine one with the other, but then some stupor begins.
How did you decide and how would you advise me to solve this issue?

Answer 1

I have the 3rd option. Modem/router D-Link DWR-730. It’s hard to find it on sale here, I bought it in Asia. Eats any Sims. I traveled half of Russia with the MTS-sim card with the Internet. You lie in a tent in the asshole of the world and watch the series online. =)
There seem to be some analogues on the Russian market, but I have not studied this issue. So offhand, I would now take this one: NETGEAR AC785. Although it is a bit pricey, the features are good. The ability to connect external antennas is especially tasty, which, for example, would be very useful for me when traveling.

Answer 2

I put the mob into the iPhone 3 and have been happy for over a year now, using it just like any other operator. Tethering works. In the absence of 3G coverage, roaming via Kyivstar is activated.

Answer 3

take Yotovsky 4G LTE modem router and live happily ever after.
