LTE SIM swap problems

I received a LET sim card with a letter setting out how to swap SIM cards. I tried this but I received a message saying there is an error and I must try again or dial 808. I have tried a number of times with no success.<br> I have tried dialling 808 without any success. No one is able to assist me. They say I must speak to activations. Try getting through to them, the system keeps sending you back to the menu no matter which option you select.<br> I called 808 a number of times yesterday. They reset my \line""; they just refer me to another department or person. <br> I eventually Spoke to Maggie on 808 who said it was an activation problem; She put me through to Activations where I spoke to Zanele who said its not their problem;they don't do that and is trying to put me through to Maggie at 808.<br> The phone rang for over 12 minutes befor"""
