Dear Sir/Madam, My sim card not working properly. Kindly activate my sim card
Yes, eventually through wear and tear USB card readers can stop working.
If your SIM card is not working in your iPhone 3G, you should check with the dealer you got the phone from. It may need to be unlocked for use with a different carrier.
No - although the handset will turn on if charged, you cannot make or receive calls, texts etc without a working SIM card.
Because if not, you could remove the SIM without shutting down the phone, which can make it stop working. I managed to remove the SIM from an older Sagem phone without removing the battery and the phone just blocked. I had to remove the battery insert the SIM and put the battery back in order to restart it.
You call your carrier and activate your sim card.
The plural form of SIM card is SIM cards.
sim card
sim card
sorry to tell you this, but i think any form of technology that involves the flow of electicity(pretty much every thing) will stop functioning in case a pole shift takes place
A SIM card adaptor will allow you to use a micro SIM in a standard SIM slot.
