Hi there, . i have been researching my question online and i've also called both the telecom call centre (useless- they put me through to the "technical desk" and i asked the question and the guy said it would not work at all), the vodafone call centre (they said it would work as long as i paid them $30 to have it unblocked).... my question is:

My bf gifted me a samsung galaxy s5 that he purchased outright from a vodafone store (bout 3 weeks ago), he hasnt used it yet- his work gave him the same phone around the same time. 

My work has me on a telecom contract, and that wont change.

i want to make my normal telecom sim into a micro sim (ive been told i can do this quite easily at a telecom store) and use the samsung galaxy s5 (why wouldnt i ?! my work supplied phone is a samsung galaxy s3 mini)....

IS THIS POSSIBLE? i know about telecom using 850/2100 frequencies (?>!) and on the vodafone site the specs for the s5 state: "GSM Band850/900/1800/1900" and there's alot of conflicting info out there.... like it;ll work on in urban areas but if i go rural it wont etc.

i live and work in rotorua central. but obviously i leave rotorua sometimes too.

the other option for me is to just make the vodafone s5 my personal phone , on prepay (i have been telecom client on prepaid and now contract via work for at least seven years, so nervous bout changing to vodafone prepaid) and keep running the mini for work??? seems like a hassle to run 2 phones, that's 2 chargers, 2 things to worry about!!! also my work often runs over to personal- friends with lots of clients etc so theyd just keep contacting work phone, the s5 might be dead!!

any advice/experience/facts greatly appreciated :)
