[Xperia Z General] nightwing369:
Had a great chat today with someone from o2. Definitely excited about the Sony Xperia Z - now just to get the best deal! :) Here are the most important points from the chat:

me: I was wondering whether in the future there will be seperate 4G tariffs to 3G tariffs, or whether they will be included as standard just like with Three. Would I need to buy a 4G data bolt on? I don't want to change from o2 to another network

o2 representative: I understand your concern. However, it'll be included in your standard tariff. You don't need to buy any other bolt on.

me: Once it is available with o2, of course

o2 representative: Yes, it'll be included in your tariff only when it'll be launched. You don't need to pay extra for 4G tariffs.

me: great so as part of the Data Allowance included in my tariff

o2 representative: Yes, but when it'll be launched. 4G data isn't included in your tariff now.

me: So if I get a 3G tariff say next month maybe; then by the time you release 4G coverage , would I need to pay any extra for that 4g ?

o2 representative: No, you don't need to pay extra for 4G. Your current tariff will be transferred to 4G network and your tariff and contact will remain as it is.

me: So it sounds like when the 4G is eventually released on o2, that it will be an increase in the possible mobile data speeds, at no extra cost

o2 representative: Yes, that's correct.

me: Will it require me to have a new sim card for 4G on o2-UK?

o2 representative: Yes, you'll have to change your sim to 4G sim but we'll send you the 4G sim when it's launched.

me: will that card work in Sony Xperia Z . Because the Sony Xperia Z is a 4G capable phone

o2 representative: Yes, it'll work for all smart phones. Don't worry, you'll get 4G sim so it'll work properly in that phone

me: great :) Right, so I was going to get my contract upgraded in March. Would I need a new sim?

o2 representative: No, you don't need to have a new sim. Your current sim will work in it.

me: So when I upgrade to that phone I simply put my current existing sim into the Sony Xperia Z

o2 representative: Absolutely correct.

me: great :) but what about when you have 4G , and 4G sim cards?

o2 representative: We'll send you the 4G sim when it's launched and transfer your number so that you can use it.

me: but before then I'll need to be using my 3G sim. So why will there be a need for a new sim when 4G is released on your network?

o2 representative: Because 4G sim will be different and more faster than 3G.

me: So it's the new sim that allows the phone to use 4G. it must be to do with the hardware of the sim, right?

o2 representative: Yes, that's right.

me: great and I will be notified as soon as you release 4G ? Will I need to request the new sim and transfer of my number, or will you simply post it to me?

o2 representative: You don't need to do anything. You'll be notified via email and we'll send you the sim via post. once you get it, just contact us and we'll transfer it. That will take 2-4 hours only.

me: And it's summer 2013 that you should start to provide 4G ?

o2 representative: As I said, we don't have any information about it so I don't want to give false commitment. We'll let you know when it's available. I hope you understand my limitations. But probably the end of 2013
