I am well aware of this. However, your primary concern seemed to be regarding triband devices and LTE connectivity, which requires eCSFB. Since the areas you mentioned already have the NV 3G side of things accepted, I expect eCSFB to be launched when those sites are LTE accepted, if not before. If your primary concern is that our market is not yet 100% covered by LTE, then this is the wrong thread for such concern.
To keep us somewhat on topic, once B41 begins to go live, I do not foresee any connectivity issues, as our market is well covered by NV 3G. The only connectivity issue will be with our poor, outdated Note II's.
