Hello,

I will be arriving in Lausanne next week and i am currently looking for a decent and cheap plan for a year.

The cheapest i found is from Lyca Mobile

https://www.lycamobile.ch/en/bundles/

They have unlimited data on all their plans which is very good. Currently, there is a sale for the M (at 9CHF) for the first 30 days. After that it is 39CHF. Their S plan is 19CHF.

Does anyone know if i can change the plan afterwards? Ie. i purcahse the 9chf (M) and then change it to S after 30 days.

Thank you.
