I have always struggled to understand the logic behind changing the sim card every time a user is changing the service provider. Surely there is technology available which would help the user use the same sim card with different service providers.
If I have to change my electric or gas provider, I dont go about changing my meter circuitry or components inside it. I just simply call my new provider and ask them to switch it and they switch it in 10-15 days without me worrying or changing anything. This should be equivalent any post pay mobile subscriber where if he/she wishes to change the provider, a call to the new provider should be sufficient.
Similarly If I have to put petrol in my car I dont go about changing the tank everytime I am using a different petrol filling station. Now this is like a pre paid subscriber. So everytime a subscriber needs to change the provider, all he should be doing it is charge the new balance with the new service provider and there you go.
I dont see that happening and neither do i see ppl talking about it. Is this too small a cost attached to it or is it not worth it. Surely if utility companies can learn something from mobile providers, mobile service providers can learn something from utilities.
Lets look at the cost implications for sim replacement. I mentioned earlier that every year there are close to 600 million sims being replaced. This number is going to increase rapidly as number of prepaid subscribers will increase. Lets assume that cost to produce a single sim is 10 cents which gives us savings of $60 million which is actually insignificant. This might though become a big cost if we were to take the present value of all the future savings as well.
But for me the bigger cost is the environment cost. As the sim cards non-biodegradable they are hurting our earth and responsible for problems which we are seeing today. So if not for short term savings, environment preservation does make a strong point to negate the case for sim replacement.
Other than that, I believe users (at least pre pay subs) would also be more empowered if changing a service provider was as easy as buying top up time from new provider.
Finally, I'll be really glad if somebody could come up with technology like this to help the operators save costs, create value for the mankind, save the environment and empower users at the same time.
