5. How to activate your SIM card if you ordered it online
Those who ordered their SIM card with either standard, next day or three hour delivery will need to log in to My amaysim to complete the activations process. The steps are slightly different depending on the delivery option.
If you chose standard delivery your SIM will be activated when you receive it. You’ll only have to complete your number transfer in My amaysim before popping you SIM card in your mobile device. Log in to My amaysim and you’ll see a button that prompts you to Start Number Transfer.
Went with three hour or next day delivery instead? You’ll need to activate your SIM My amaysim and also transfer your number if you’ve chosen to bring it over to amaysim. Your mobile plan you’ve chosen won’t kick in until after your number transfer and SIM activation have finished.
不是很懂这句话if you chose standard delivery your SIM will be activated when you receive it什么意思?说的是如果寄到了就自动激活开始计费吗?这样好像不怎么合理啊。
