Today I changed sim in my phone of reliance and inserted sim of vodafone. But forgot to change APN. It remained set at rcomnet. And started browsing. It was working. I didn't do it intentionally. After some time I realised that I have forgot to APN romnet with vodafone gprs. I was amazed to see that my net was working with rcomnet APN with vodafone sim. I have data balance in both.
Just want to ask how did it happen? Anybody have any idea about this?
