Thought I would check out this offer, I noticed that the offer requires me to upgrade to a 4G plan. So I checked out the 4G/3G plan differenrces. I noticed that the 4G plan required me to cancel my national roaming, something the 4G plan does not seem to replace (is this right?). In addition I have a discount ($4.23) that they discontinued but I get to keep until renewal or upgrade. I am in an area that does not have 4G but thought it might be nice to have if I travel to an area with it.
From my reading it seems that the 4510L 4G seems to have problems (logging out after 30 min., not connecting while charging).
Can anyone suggest why I should consider upgrading.
