London is a wonderfully diverse city. Here are some useful apps and hints:
- Citymapper is the app for public transport.
- 4G on Lycamobile works really great, just do not try to compile
meta-raspberryYocto layer through it as the limits are quite low for such experiments. Compiling Buildroot is OK though as it has much less dependencies to download… :-)
- Use public libraries! They are great! But even there it’s better to use internet over 4G.
- The equivalent of Israeli Rav Kav travel card is Oyster.
