I have a rooted Samsung Galaxy S2 running the stock Samsung ROM (no custom ROMs ever). Of late, I notice that every few minutes, a toast pops up saying 'Refreshing SIM data'. If the screen had been blanked earlier, it reactivates, and this is annoying, especially at night. I don't know if this is relevant, but only recently I got 3G activated (Vodafone, Bangalore,India) and it didn't happen before.
Anyone seen this, and is there a workaround or fix?
