The main crossings exist and cross-border coaches do run at times, but the posts close temporarily quite often and sometimes the whole border closes at once. Do not build an itinerary that assumes you will get through on a particular day. Confirm with the coach operator on the morning itself, and have a plan for what you do if the crossing shuts while you are on the way.

Somewhat. Most masts have backup power, but a long outage can still take one out of service for a while. The bigger problem for you is charging your own devices. Carry at least one high-capacity power bank, top everything up whenever the power is on, and keep the documents and maps you need saved on the phone rather than in the cloud.
