Can someone help. I bought a Huawei U8300 Android Phone (unlocked) but my telstra sim is not recognized. I tried a boost sim and a virgin sim also, but the phone still says, "no sim, emergency calls only". I bought the darn thing on Ebay brand new. I took it to the Telstra shop, they gave me a replacement sim but still not functioning. Can anyone shed some light on this, or is the phone faulty?
