How can I get iCloud?

The cellular carrier that you use has no effect on iCloud. You can even access iCloud from computers which have no cellular carrier, via wi-fi.

See the information in iCloud - Apple

Also note that iCloud includes a variety of services so you may want to reply with more information about what it is that you are wanting to do.

So is my bill up to date now? There is some confusion

The only bill I can think of that is directly related to iCloud is if you have upgraded your iCloud storage from the free 5GB plan to a larger storage plan.

This is primarily a user-to-user support forum; other Apple users like you. We don't have access to information about charges to your account. See each of the steps in the following instructions. They include information on contacting Apple Support if the other steps don't help: If you see 'apple.com/bill' on your billing statement - Apple Support

or go to Subscriptions and Billing - Official Apple Support
