UNLOCKED for use with any GSM 850/1900 MHz Wireless Service Carrier’s

SIM Card for Voice Services ONLY!

The NOKIA 6010 may or may

NOT be unlocked for data services depending on which Wireless Service

Carrier’s BRAND is on the phone.

In the case of a T-Mobile

branded phone, it is FIRMWARE LOCKED to T-Mobile for Mobile Internet

(t-zones), Multimedia Messaging Service (MMS) and other data services.

A T-Mobile SIM Card is required to use data services.
