Final answer:
The inclusion of a T-Mobile SIM card with a new device purchase varies and is not automatically assumed to be included. Additional fees may apply or it may be part of a service agreement. Verification with the carrier or retailer is recommended.
Step-by-step explanation:
The inclusion of a T-Mobile provided SIM card with the purchase of a new device may vary depending on the specific terms and offers in place at the time of purchase. Generally, it is not automatically assumed that a SIM card is included in the purchase price of a new device. The costs may be bundled into a plan or require an additional fee. Typically, the details regarding the inclusion of SIM cards and associated costs are clarified by the carrier or the retailer at the point of purchase or within the terms of the service agreement. Therefore, the assumption that a T-Mobile SIM card is included with the device purchase price without additional costs is not necessarily true.
