That's why I wrote about a "soft change". OpenCall don't forces, but only recommends to change or "upgrade" the network from Vodafone to O2. All the old features will remain on your old SIM and there is no shut-off date planned so far. So you can keep your old SIM as usual (for 6 months) and change to the new network the next time when you are in CZ or even keep the old SIM.
