Call Quality of all networks in Ghana



Call quality depends on the number you're calling*, your network*, 3G or 2G being used*, congestion, signal strength, interference, noise, how both networks are connected together, and audio processing done by phones.


* Provided by tables on this page.


Audio compression formats and bit rates were taken from calls made on phones that support WB-AMR. Results may differ on phones that don't support it. WB-AMR(Wideband Adaptive Multi-Rate) can transfer more kinds of sound waves compared to NB-AMR(Narrowband Adaptive Multi-Rate).


Vodafone Ghana's 4G was excluded because CSFB is used for calls (calls are either on 3G or on 2G).


This is a list of the best audio compression format and bit rate known for each combination. A higher quality may be available.


Calls may have a low quality or may drop if the signal is bad. 


Even in compatible phones, WB-AMR is not guaranteed, NB-AMR/EFR may be negotiated in some cases.


Even though WhatsApp calls are more likely to provide a higher quality, 2G/3G calls are more likely to skip traffic.


"Shortcode" includes 1303 on MTN.


2G doesn't reuse frequencies like 3G, making it less likely to have a call drop due to interference, but it is still possible.


On 3G and 4G, voice and data can be used simultaneously.


Landlines, international calls, and roaming were not tested.


The NCA publishes statistics about call quality. See https://google.com/search?q="quality+of+service"+site:nca.org.gh+filetype:pdf and https://google.com/search?q=site:mos.nca.org.gh

Unofficial list of 250+ Shortcodes (USSD) for MTN Ghana +updates

This page is not provided by nor affiliated with MTN Ghana, though it could be useful on MTN, and maybe other MNOs (AirtelTigo, Glo, Vodafone). It is not guaranteed to be complete or accurate. Request addition/removal below. Before dialing USSD codes, the mobile phone shall be within 2G or 3G coverage. If connected to 4G, the mobile phone shall be allowed to use 2G or 3G automatically, not "4G only" also known as "LTE only". In the event of only 4G being available, seek alternatives, including MyMTN. To the greatest extent possible, only the user is responsible for any unintended operation after use, including but not limited to "accidentally subscribing to premium services", try dialing *175# to unsubscribe. Use at your own risk. All trademarks are the property of their respective owners. Listing of a code does not imply endorsement. Do not pay anyone who claims that your code will be added to this page. No codes were added that way. Th...

MTN Ghana 216.47GB(or 182.08GB) for 399GHS, more details

This bundle is now removed from *138# and the MyMTN app, but there's 92.88GB for 350GHS. The purchase of 399GHS grants the user 216.47GB(now 214.09GB, after taking into account updated taxes 182.08GB) of data and a 50% bonus if bought on 4G . There is an additional 25% Terrific Thursday bonus if bought on Thursday. The 4G Bonus now requires that the bundle be bought with MobileMoney in the MyMTN app. Place the device on 4G and do not gift the bundle. It is OK if it temporarily switched to 3G or 2G during the use of *138# or *170#. If you are not given the 4G bonus, you will be given it later. Alternatively, contacting the network may have you granted the bonus earlier. Even without that, you'll eventually be given the bonus. Even if it's purchased with 4G, the bundle can be used on 3G or 2G. The bonus expires after 1 week, precisely 168 hours after purchase. Quite like how milk expires: after a week or so, you'll have to dispose of it all no matter how much is lef...

MTN Ghana VoLTE now available for some subscribers

MTN Ghana VoLTE now available for some subscribers Meaning of VoLTE VoLTE means Voice over LTE, and LTE can be explained as 4G. This means voice calls are possible on 4G, without having to rely on the temporary use of 3G or 2G during voice calls. Though WhatsApp could be used for voice calls on 4G even without VoLTE, VoLTE skips queues and can be better where the network is slow . VoLTE has a priority of 5 or 1, and data can have a priority of 6. WhatsApp does not skip queues. Improved call quality This is by using Adaptive Multi Rate Wideband at up to 23.85Kbps* instead of using Adaptive Multi Rate Wideband at up to 12.65Kbps. However, calls to AirtelTigo numbers, Glo numbers, and shortcodes are instead with Adaptive Multi Rate Narrowband at up to 12.2Kbps*. This includes shortcodes that play music. * Subject to change. Message There is a message associated with VoLTE. "Y'ello! You can now enjoy improved voice calls and data activities concurrently with the VoLTE service. To ...
