Hello Martini,
I could share with you a lot about Yumbe as I managed some ICT services in the area.
There are various considerations when it comes to Yumbe as part of West Nile.
Challenges
The town has some blackspots, given that the infrastructure is not planned.
There are power outages at times prolonged ones.
Weather is another factor, for generation of power and keep ICT infra running at standard temperature ranges.
Solutions
You need to have at least two of the networks from MTN, Africell or Airtel to understand what will work for you.
Otherwise you can go for office grade internet which is a fixed installation.
Include an inverter to cater for power outages and clean power.
All this depends on your posting and the benefits for your position. Dig in from your pocket, it won't cost much when in Uganda.
Enjoy and have fun.
