FREQUENTLY ASKED QUESTIONS

Unless otherwise noted, all phones sold on OneSimCard.com come with our standard 90-day replacement warranty. This warranty covers any mechanical defects, but does not include damage due to Acts of God, neglect, water damage, or other intentional or unintentional abuses of the phone. OneSimCard does offer extended warranties available for purchase.

Sometimes when moving from the USA, Canada or Mexico to another country, the SIM card will need to be reset to properly register on a new country roaming network.

• If you have the OneSimCard Menu on your phone (it may be called Sim Application Menu on iPhones or SIM Toolkit on Androids), go to the menu, scroll down to Settings and enter Service Code 2003 and confirm, then Code 000 and confirm. For older SIM cards after this enter Service Code 1101 and confirm. Turn the phone off and then back on. 
  
  
• If you do not have access to the OneSimCard Menu then turn off your phone, remove the battery for 20 seconds, reinstall the battery and then turn back on your phone.

Note: You can always dial 00 instead of + when making outgoing calls. For example, to reach OneSimCard customer service in the USA you can just dial 001 617 3138888.

You should consult the phone manual for this info. Different manufacturers have specific ways to access the '+' key, so make sure you know yours.

Here are few known ways:

• Bosch: Press and hold the star (*) key until the "+" sign appears.
• Motorola: Press and hold the zero key until the "+" sign appears.
• Nokia: Press the star (*) key twice in rapid succession.
• Pocket PC: Pull up the keyboard, hit the <123> button in the top left corner, and select "+" from the resulting screen.
• Samsung: Press and hold the zero key until the "+" sign appears.
• Sony Ericsson: Press and hold the zero key until the "+" sign appears.
• Treo 270: Press the blue button and then the "G" key.

There can be a number of reasons why a battery does not hold a charge. Excluding the possibility of it being a faulty battery, there is another important factor to consider. If your phone is not registered on a roaming network, the battery will drain very quickly as the phone is constantly searching for a network to register on. So, if you get on a 6 hour flight and do not turn the phone off, or put it into airplane mode, by the time you land at the airport your battery will be drained and you will not be able to call back home.

The same thing will happen in those areas with spotty or weak signal network coverage - the battery will drain very fast. It is always a good idea to have an extra battery with you when you travel abroad.

 

It does not cost more to dial an international mobile number using OneSimCard service on traditional cellular connections. You will receive the same very low per minute rate whether calling to a mobile phone or to a land line. 

 

For OneSim VoIP, the cost of calling Mobile numbers is typically higher than calling landlines, but this method is still less than traditional voice calls in most countries..
