LTE Activation on my Sim card

I am trying for more than three weeks now to get LTE activated on my sim card after i did a sim swap at the Vodacom shop in Woodmead.<br> <br> LTE was working perfectly before the sim swap !!!<br> <br> I bought a new Iphone 6 and had to get a \nano\" sim for it. My previous phone had a normal \"micro\" sim.<br> <br> The sim swap was done successfully ... except for only getting a 3G signal. I tested the phone with my wifes sim card (4G) and the phone worked perfectly with her sim. I also had the phone checked out at the Apple Istore and 4G is working perfectly on the device. <br> <br> I then started the \"rocket science\" experience of trying to get Vodacom Customer Care to activate 4G on my sim card. It is now 3 weeks later and absolutely no joy ... 4G is still not activated !!!<br> <br> I called them 9 times and also contacted the Vodashop on numerous occasions. No 4G yet !!!<br> <br> Is this really such \"rocket science\" or a simple \"tick\" that a 3 year old can do ???<br> <br> What else on earth do i have to do to get LTE activated ???<br> That was working perfectly until the sim swap 3 weeks ago.<br> "
