Did it stop on the day the merger was signed? If not, when?

Differeent bands make no difference to roaming. I can go roam in
Australia or Europe that use different bands than in Canada.

This was an issue in early phones that supported only 1 band, then
supported 2 or 3, then 4. But they have now supported a whole bunch of
bands for a long time.

If Sprint has some "odd" spectrum for which there is no handset support
on LTE or 5G, it may not deploy it until/unless it gains support from
everyone. It learned its lesson having to put 3G on 1700 which nobody
else in USA had.


Considering T-Mobile won't shutdown CDMA till early next year at
learliest, I suspect the current arrangement continues till then.  The
faster T-Mo converts Sprint customers to GSM-only, the less CDMA it
needs to buy from Verizon.

But once T-Nio is a single network with LTE for both voice and data, it
can shop around for which of AT&T or Verizon it gets its LTE from. I
beleive it has FCC mandate to get some from AT&T, but what if Verizon
offers better price?

This is where monopolistic behaviour comes in. Verizon may prefer to
lose the roaming revenue so it can market its better coverage nobody
else has.
