Because Public Mobile is no longer selling handsets, it is ppl's responsibility to ensure that the phones they buy and port over are 100% Compatable.
Public Mobile uses these Frequency spectrums:
3G: 850/1900 MHZ
4G LTE: 1700/2100 MHZ
4G LTE Advance: 700 MHZ ( Side note: This frequency isn't available as of yet, Telus needs to build and fully assemble this, and Handsets need to have this frequency built-in to fully take advantage of this particular spectrum)
The HSPA+4G Network has NO 2G GSM Fall back, so Check prior to purchasing.

To check out whether your handset will work on the Network
IF YOU BUY HANDSET FROM a KOODO Physical store or Telus's Online store, The Handsets Most of the time don't require you to unlock, though Some might. If You buy from a Koodo Store, Handsets with the PURPLE LABEL on them can be bought outright W/O needing to become a Koodo Client
Telus's Physical Stores DON'T PERMIT Outright purchases unless you become a Telus Client.
Telus's Online Store is THE ONLY EXCEPTION; NOT ALL HANDSETS can be bought outright until 90 DAYS after their initial release
