Have you ever stopped to think that eSIM doesn't seem to be a new technology?
Yes, for those who were born until the end of the 90s in Angola, I believe you should remember that Movicel, unlike Unitel, only sold telephones, telephones that already worked without chips, they used CDMA technology (Multiple Access by Code Division) .
Which seems to be exactly what we know today as an eSIM, only with updates such as:
- Possibility of having more than 1 number on the same phone without a SIM card and from different operators;
- Transferring numbers from one phone to another
They also improve the security issue, in case of loss or theft of the phone, even turned off the eSIM continues to emit the GPS signal;
Without forgetting the environmental issue, which includes the reduction in the manufacturing of SIM Cards, which, as everyone should know, are made of plastic, which is one of the biggest environmental crises.
Well, the eSIM is a virtual SIM, which the customer configures through a QR Code.
It seems that once again, the adage that “The wheel has already been invented” prevails. Improving a product/service is also innovation, which seems to be the case from CDMA to eSIM.
