What do I need to know before moving to Lyon?

"Expatriates should be aware that Lyon is the third largest city in France. Though the city itself is quite diverse, the overall culture of France is still dominant. There is an efficient public transportation system, making the city easy to navigate. However, it is important to keep in mind that most Lyon-based professionals speak French in their day-to-day lives. Expats should also consider investing in a local SIM card for their mobile phone for easier communication. Furthermore, some areas may be more expensive to live than others and it is advisable to research housing costs and availability before making a move. Lastly, expats should be open to learning new customs and traditions as they come to terms with their new life in Lyon," mentioned another expat when asked about moving to Lyon, France, France.
