I can not understand how Softbank come to their minimum cost ie. 3,860 for the 32gb and 3,380 for the 16gb.<snip>
Here's how I understand it:
iPhone minimum plan charges (32GB 3GS):
_315 yen --> S! Basic Pack (i)
_980 yen --> White Plan (for calling)
___0 Yen --> Phone calls
1029 Yen --> Data plan
1920 Yen --> Rebate credit from SoftBank
2880 Yen --> Handset cost (24 payments)
3284 Yen --> Monthly cost
iPhone minimum plan charges (16GB 3GS):
_315 yen --> S! Basic Pack (i)
_980 yen --> White Plan (for calling)
___0 Yen --> Phone calls
1029 Yen --> Data plan
1920 Yen --> Rebate credit from SoftBank
2400 Yen --> Handset cost (24 payments)
2804 Yen --> Monthly cost
iPhone minimum plan charges (8GB 3G):
_315 yen --> S! Basic Pack (i)
_980 yen --> White Plan (for calling)
___0 Yen --> Phone calls
1029 Yen --> Data plan
1280 Yen --> Rebate credit from SoftBank
1280 Yen --> Handset cost (24 payments)
2324 Yen --> Monthly cost
On this
page the 8GB cost figures match but the 32GB & 16GB 3GS models do not. There is a difference of 576 yen.
Not sure why that is. My guess is:
- A simple math error.
- They are including optional services but not listing them.
Regarding optional services, Voicemail is 315 per month. If you receive many voice messages, it might be a worthwhile option to consider.
You mentioned that you will be traveling at times. When I asked my local SoftBank shop about changing from White Plan (WP) to Double White Plan (DWP) or vice versa, they said that it is done on a billing cycle. So if the billing period is the 11th to the 10th, then before the 11th you would need to change your plan for it to take effect in the next billing period. While not sure, I assume that this applies to optional services as well.
Please tell us what you find out when you check with your local SoftBank shop.
