- We have a 27 MHz city band transmitter/receiver. So far we never used it, but we expect to need it in Australia;
- Walkie-talkies to communicate when we travel in two cars with family or friends;
- We had a borrowed satellite phone with us, mainly to be able to receive urgent messages from home; however, as both purchase price of the phone and subscription fees are high we later replaced it with a satellite messenger . This solution is much less expensive and serves the purpose just as well;
- For less urgent issues we use mainly WhatsApp and email. In most countries we bought a prepaid SIM with data package;
- WiFi was available at many camp sites in South America and increasingly in Africa. Check iOverlander for details per camping;
- In Iran, Sudan and to a certain level also in Uganda we experienced restrictions in internet access, for example Facebook or Weebly, the site that we use to create our website. We used some VPN-tools to circumvent the restrictions, but access stayed difficult and became slow. Make sure that you have downloaded and configured the required apps before you enter a country with restrictions. we also have sent a newsletter instead of updating the site if that was impossible (also if the internet was too slow).
