Editing GSM frequency bands (section)

=== Frequency mixing between GSM 900/1800 and GSM 850/1900 ===

Some countries in Central and South America have allocated spectrum in the 900&nbsp;MHz and 1800&nbsp;MHz bands for GSM in addition to the common GSM deployments at 850&nbsp;MHz and 1900&nbsp;MHz for ITU-Region 2 (Americas). The result therefore is a mixture of usage in the Americas that requires travelers to confirm that the devices they have are compatible with the bands of the network at their destination. [[Frequency compatibility]] problems can be avoided through the use of multi-band (tri-band or, especially, quad-band) device.

The following countries are mixing GSM 900/1800 and GSM 850/1900 bands:<ref>{{cite web |url=http://www.worldtimezone.com/gsm.html |title=GSM Bands information by country |publisher=WorldTimeZone.com |date=2016-01-16 |access-date=2016-02-06}}</ref>
