1. They share the same coverage as Celcom 2G and 3G. They use their own 4G infra instead of using Celcom's.
2. No. Their signal is not as goof as DiGi or Maxis. They are still new and you need to give them some time.
3. No contract.
4.RM100+ for the first time and RM79 for the following months.

The share the same infra but they they dont share the same network.

When you use webe, you are connnected to Celcom's infra (base station) then the data that you send goes to webe's network instead of going to celcom's network. So when you check your IP on website, it will say you are using webe instead of showing Celcom.

RM100 as upfront payment. It will deduct monthly.
Plus 6% GST.
Total payable for 1st payment is RM106.00 include postage to your address.

I just did it few days ago and waiting for courier.
Expected today and hope to join the banwagon.
