I walked the Norte without a mobile phone, a guide, or a map and I don't speak Spanish. A few tips
1) Ask the hospitalero at the alberge each night what your options are for the next day. They are usually very well informed about the next day or so's walking.
2) Just follow the arrows. Its almost impossible to get lost. If you do lose track, just ask any local just by gesturing ahead and asking "Camino?" They will soon put you straight. Carry a small torch (that's a flashlight for you North Americans), to find you way predawn. You soon get a sense of where to look for arrows.
3) Talk to your fellow pilgrims, particularly the Germans who are always well informed and have excellent guides, speak English well and have done their research.
4) Check at the tourist information office in any town, which will be signposted to with the internationally recognised sign. They usually are well informed and have local maps.
5) Don't take it all too seriously. I know full well the traipsing along through mud, in pouring rain with sore shoulders, legs, feet covered in blisters, not knowing how far until the next alberge or cafe can be really hard work, but always found a hot shower, a laugh with fellow pilgrims and a glass (or two) of vino tinto set me up to do it all again the next day.
6) I found the advice that "in the first week you adjust physically, the second week mentally and in the third week you start to enjoy yourself" to be very true. I found myself wishing that the camino could go on for ever. In the meantime, ease the pain with orojo the local fire water...
