I have just received my iPhone 4S ordered online. I don't have a microsim card that iPhone 4S would need to me to. I don't wish to pay extra to buy a micro sim card since it doesn't give much improvement. I did a search and found out that I could cut my ordinary 3G sim card to the size of a micro sim card. And I did this.
So now, I put that trimmed micro sim card into my iPhone 4S and it worked. But, the reception meter has only 2 bars all the time! The phone may be able to access the web and send sms through the cellular network but having only 2 out of 5 bars at the reception meter makes me feel totally unsafe; I am doing all of these at my home, where the reception signals are usually very strong.
When I put the same trimmed sim card into another iPhone 3GS, the reception also has only 2 bars. But when I put the trimmed sim card into an iPhone 2G, it has 5 bars.
What's wrong? Is it my iPhone 4S or the sim card that is having the problem? What problem am I having and what else can I do?
So the 5 signal bars on iPhone 2G is merely the 2G network. When the 2-bars 3G signal on my iPhone 4S drops to only the 2G network, it also has 4-5 bars of signal strength but that's 2G. Does trimmed SIM card has problems with 3G networks?
