Here is the explanation:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400\">The reason the MMI code is invalid is because there is a problem with the cellular network on your cellphone.\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400\">Then, other causes could also be due to interference or bugs in the software system on the cellphone.\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400\">Apart from that, this can also be caused by errors in the network settings on the cellphone.<\/span><\/li>\n<li><span style=\"font-weight: 400\">And finally, the cause of the invalid MMI code is due to interference with the cellular operator.<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400\">How to Solve Connection Problems or Invalid MMI Code<\/span><\/h2>\n<figure id=\"attachment_143009\" aria-describedby=\"caption-attachment-143009\" style=\"width: 1144px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-143009\" src=\"https:\/\/storage.googleapis.com\/cdn.vcgamers.com\/news\/wp-content\/uploads\/2024\/08\/masalah-sambungan-atau-kode-mmi-tidak-valid-alphr.jpg\" alt=\"connection problem or invalid mmi code (2)\" width=\"1144\" height=\"640\" srcset=\"https:\/\/storage.googleapis.com\/cdn.vcgamers.com\/news\/wp-content\/uploads\/2024\/08\/masalah-sambungan-atau-kode-mmi-tidak-valid-alphr.jpg 1144w, https:\/\/storage.googleapis.com\/cdn.vcgamers.com\/news\/wp-content\/uploads\/2024\/08\/masalah-sambungan-atau-kode-mmi-tidak-valid-alphr-300x168.jpg 300w, https:\/\/storage.googleapis.com\/cdn.vcgamers.com\/news\/wp-content\/uploads\/2024\/08\/masalah-sambungan-atau-kode-mmi-tidak-valid-alphr-1024x573.jpg 1024w, https:\/\/storage.googleapis.com\/cdn.vcgamers.com\/news\/wp-content\/uploads\/2024\/08\/masalah-sambungan-atau-kode-mmi-tidak-valid-alphr-768x430.jpg 768w, https:\/\/storage.googleapis.com\/cdn.vcgamers.com\/news\/wp-content\/uploads\/2024\/08\/masalah-sambungan-atau-kode-mmi-tidak-valid-alphr-18x10.jpg 18w, https:\/\/storage.googleapis.com\/cdn.vcgamers.com\/news\/wp-content\/uploads\/2024\/08\/masalah-sambungan-atau-kode-mmi-tidak-valid-alphr-250x140.jpg 250w\" sizes=\"(max-width: 1144px) 100vw, 1144px\" \/><figcaption id=\"caption-attachment-143009\" class=\"wp-caption-text\">Invalid MMI Code. Source: Alphr<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400\">There are many ways to overcome invalid MMI codes for all operators, for more details, let&#039;s look at the following discussion:<\/span><\/p>\n<h3><span style=\"font-weight: 400\">Restart HP<\/span><\/h3>\n<p><span style=\"font-weight: 400\">The first way to solve the invalid MMI code problem is to restart the smartphone. Here&#039;s how to restart your phone easily and safely:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400\"> Hold the Power button and the Home button simultaneously until the phone turns off and starts vibrating, wait for it to restart.<\/span><\/li>\n<li><span style=\"font-weight: 400\"> Alternatively, you can press and hold the Power button until the Shutdown options menu appears, then select &#039;Restart&#039;.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400\">Check Network Settings<\/span><\/h3>\n<p><span style=\"font-weight: 400\">The steps to access your network settings will vary by phone type, but the concept is the same.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">First you have to go to settings. Then, select &#039;Network Connections&#039;, then select &#039;Mobile Network&#039;.<\/span><\/p>\n<h3><span style=\"font-weight: 400\">Use Airplane Mode<\/span><\/h3>\n<p><span style=\"font-weight: 400\">Turning on airplane mode for a while and then turning it off can also work to solve this MMI error code issue.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">The method is quite easy, you just need to open Settings and change Airplane Mode to &#039;On&#039;. Wait about 10-30 seconds then change Airplane Mode to &#039;Off&#039;.<\/span><\/p>\n<h3><span style=\"font-weight: 400\">Change Prefix Code<\/span><\/h3>\n<p><span style=\"font-weight: 400\">Another way to fix connection problems or invalid MMI code is to add a comma at the end of the prefix code.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">When a comma is added, it forces the operation to execute and ignores any errors.<\/span><\/p>\n<p><span style=\"font-weight: 400\">For example, if the Prefix code is (*2904*7#), add a comma at the end, like this (*2904*7#,). You can use the (+) symbol after (*) similar to this (*+2904*7#).<\/span><\/p>\n<h3><span style=\"font-weight: 400\">Activating Radio and Activating IMS via SMS<\/span><\/h3>\n<p><span style=\"font-weight: 400\">The last way you can do is to activate the radio and IMS via SMS. Here&#039;s how to do it:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400\"> Go to the keypad. Type *#*#4636#*#* but do not press the send button, it will automatically appear in &#039;Service&#039; mode.<\/span><\/li>\n<li><span style=\"font-weight: 400\"> Then go to &#039;Service&#039; mode, select &#039;Device information&#039; or &#039;Phone information&#039;. Select &#039;Run Ping test&#039;. Click the &#039;Turn Radio Off&#039; button and select &#039;Restart&#039;.<\/span><\/li>\n<\/ul>\n<blockquote><p><strong><em>Also read:<\/em><\/strong><\/p>\n<ul>\n<li><strong><em><a
