The R stands for Roaming. It is considered a roaming because the SIM Card is actually came from NL/UK (or else)
, but it provisioned with a Swiss number. The SIM Card does not contain your phone number. It contain the ICCID which is later paired by the operator with an IMSI (do google it
). Thats why you can change a sim card but keep the same phone number...
If you want to use the internet on Lycamobile, enable data roaming, then add new APN on the mobile setting of the sim card. APN Info:
APN Name: Lyca Internet
APN Address: data.lycamobile.ch
Now, that internet is activated, buy lyca data package.
It start from CHF 1.25 for 120 Mb. More details here
Without the data package, the data connection cost CHF 0.10 / Mb.
Hope that helps
