eCallChina STRONGLY recommends our customers to cancel your cell phone and/or home phone international long distance calling plan. You may not know you have such a plan because this service is added to customers' calling plans without their knowledge. If you are not sure, check your bill or contact our plan service provider. Charges by wireless and land-based phone service providers for overseas long distance calls can be unreasonably high. eCallChina can take no responsibility for the calls go through your long distance plan without using our phone card, or fail to use our phone card properly. Cancel your international long distance plan can protect you from such kind of mistake. Rely instead on the local and 800 numbers provided to eCallChina's phone card customers.
