You’ll find internet now available on some long-distance buses. You can also get a prepaid internet device (either a USB one that plugs in to your laptop or, more conveniently, a wifi hotspot to connect various devices) where you buy a sim and recharge with prepaid cards. As plans are always changing, it’s hard to recommend one company in particular. Typically, with a wifi hotspot, you’ll have to carefully watch your consumption as it can run out quickly. If you do decide for one with prepaid cards, be sure to check the expiry. No point in loading a lot of balance on the device only to have it expire before you use it.
Many of the wifi signals publically-available are not meant for streaming and often not meant for VoIP (voice over internet protocol) phone calls such as over Skype. That’s best done on a network where you are the only user.
