The original idea was to have a type of text that could be more attention grabbing than standard SMS.\u00a0<\/p>\n<p><\/p>\n<p><\/p>\n<p>Because the message appears on the screen, in full, without having to press any buttons or unlock the phone, the message is more likely to be read.<\/p>\n<p><\/p>\n<p><\/p>\n<p>That\u2019s the logic.<\/p>\n<p><\/p>\n<p><\/p>\n<p>This made sense before the arrival of the smartphone when mobiles had very limited functionality compared to today\u2019s phones.<\/p>\n<p><\/p>\n<p><\/p>\n<p>Flash SMS was invented in an era when phones were able to make calls, receive texts and that\u2019s about it. It was seen as rather an impressive tool that could genuinely make some impact.<\/p>\n<p><\/p>\n<p><\/p>\n<p>It never did.<\/p>\n<p><\/p>\n<p><\/p>\n<h2 class=\"wp-block-heading\"><strong>What are the downsides of Flash SMS?<\/strong><\/h2>\n<p><\/p>\n<p><\/p>\n<p>Flash SMS never really took off.<\/p>\n<p><\/p>\n<p><\/p>\n<p>The average person has never heard of it or ever received one.<\/p>\n<p><\/p>\n<p><\/p>\n<p>The major flaw with flash SMS is that the message isn\u2019t stored on the phone. As soon as it\u2019s \u2018dismissed\u2019, it\u2019s gone for good.<\/p>\n<p><\/p>\n<p><\/p>\n<p>If the message contained any important information like a\u00a0<strong><a href=\"https:\/\/thesmsworks.co.uk\/guide-2fa-sms\">2fa\u00a0security code<\/a><\/strong>\u00a0or an appointment time, then that information is lost.<\/p>\n<p><\/p>\n<p><\/p>\n<p>There\u2019s also a major security issue with flash SMS . The message arrives on the phone, in full, on the lock screen. If that message contains any sensitive information, then that\u2019s freely available to be read by anyone that can see the phone. It\u2019s totally insecure.<\/p>\n<p><\/p>\n<p><\/p>\n<p>So flash SMS doesn\u2019t really serve any purpose. 95% of all texts sent are read within 5 minutes anyway, so further attention grabbing isn\u2019t really necessary.<\/p>\n<p><\/p>\n<p><\/p>\n<h2 class=\"wp-block-heading\"><strong>Is it safe to open a flash SMS?<\/strong><\/h2>\n<p><\/p>\n<p><\/p>\n<p>Flash SMS just arrive on the phone, so there\u2019s no requirement to open them in the way that you\u2019d open a standard text.<\/p>\n<p><\/p>\n<p><\/p>\n<p>The technology is perfectly safe though and doesn\u2019t present any security or virus threat.<\/p>\n<p><\/p>\n<p><\/p>\n<h2 class=\"wp-block-heading\"><strong>Should I use Flash SMS for contacting my customers?<\/strong><\/h2>\n<p><\/p>\n<p><\/p>\n<p>In a word, no.\u00a0<\/p>\n<p><\/p>\n<p><\/p>\n<p>Flash SMS was not a great idea back in the 90s and it\u2019s still not a great idea. You\u2019re more likely to alarm your customers than impress them.\u00a0<\/p>\n<p><\/p>\n<p><\/p>\n<p>Because the message disappears once you dismiss it, you\u2019ll probably generate a huge amount of support from customers wanting you to send the message again because they couldn\u2019t save the content.<\/p>\n<p><\/p>\n<p><\/p>\n<p>I don\u2019t know of a single company that has used flash SMS effectively and continues to use it.<\/p>\n<h2><strong>Flash SMS on iOS<\/strong><\/h2>\n<p>Starting in iOS 14, Apple started to conditionally treat Flash SMS like regular text messages.
