Getting prepaid mobile broad band in Italy

[wco81]

OK, found some info. including some coverage map info. But it's confusing, there are so many options.

Can someone outline the terms of the keys offered by Vodaphone and TIM?

Are these unlocked so that I can use them in other countries later?

Or are they locked and on contract with a required monthly top up?

This one from Vodaphone looks too cheap to be unlocked and seems to include some time as well:

TIM has a lot of them and they come in many configurations. This Huawei E1692 for instance is available in a 59 Euro SKU and a 99 Euro SKU:

HUAWEI Chiavetta Internet E1692 7.2 MEGA - TIM

They both come with a Tim card with 5 Euro of prepaid traffic.

The 59 Euro also includes 5 hours of Internet.

The 99 Euro bundle says 1 year of navigation (40 hours per month for 12 months).

Can't tell if either of these are unlocked or if there are required top ups.

Or whether you can go to use say 100 hours in a month by recharging.

TIM has a good coverage map search:

Vodaphone has a map search but it returns no results. Tried Milan, Rome, nothing:
