Most of today's standard SIM cards have either 64 or 128kb of storage capacity, and they are normally used for holding mobile phone numbers, text messages and other data.


This means thousands of essential information about pregnancy can be pre-installed as 'contacts' or 'text messages' then sent to wherever they are needed.


The hook of this idea is that almost ALL mobile phones use the universal size SIM card (except the latest such as iPhone 4) therefore this SIM card can be inserted and pre-installed information can be read from their own device, whether it's a Nokia 1100 in Bangladesh or Motorola Startec in Philippine. Then their mobile phones turns into a learning tool.


64kb sounds very little, but it can hold hundreds of text messages. What's even more, the capacity of SIM card can be extended up to 256MB, which means it can embrace not only text based information but images as well, which will be very handy under a low-literacy context.


After the birth, the SIM card can be passed onto other pregnant women in the same community.

What is the minimum level of mobile technology needed for this concept?

A device which has 'text function'

Which partners could help realise and deliver this solution?

  • Nokia
