Bandwidth on Optus Sleek

How do you change the bandwidth on an unlocked Optus Sleek to allow calls to be made using a Telstra SIM

Re: Bandwith

So you have 2 issues.
The device would be locked ot Optus as its a prepaid device (so most likely a fee to unlock it)

and the device does not support 3g 850Mhz - which is what Telstra uses for calls via 3g (not likely that you could use calls over 4g with this device)

Supported Bands:

UMTS: 900/1900/2100 MHz
LTE: FDD 1/3/7/26/28 and TDD 38/40

Did someone on Yes Crowd answer your question?
