Abstract

A SIM module includes a SIM and a plastic support on which the SIM is attached. A discontinuity channel between the plastic support and the SIM is formed all around the SIM, the discontinuity channel being interrupted in at least two points of the plastic support attaching the SIM to the plastic support. The points are on a short side and on a long side of the SIM.

First claim

That which is claimed:

1. A Subscriber Identity Module (SIM) comprising:
a SIM having at least one long side and one short side;
a plastic support on which the SIM is attached;
a discontinuity channel between the plastic support and the SIM, and around the SIM, said discontinuity channel being interrupted by only first and second attachment points each defined by a triangular shaped portion of said plastic support, the first attachment point being at the short side and the second attachment at the long side of the SIM; and
a lateral recess formed on each side of each attachment point and extending no longer than an edge of a base of the triangular shaped portion to let the plastic support be broken between the breaking point and the opposing breaking point without precut lines when the SIM is detached, a minimum size of each lateral recess makes the long side and the short side of the SIM planar and protects undesirable substances to be filled in each lateral recess.

2. The SIM module according to claim 1 , wherein a depth of said lateral recess decreases proportionally to a distance from said attachment point.

3. The SIM module according to claim 1 , wherein said discontinuity channel has a width between 1/7 and 1/15 of said short side of the SIM.

4. A Subscriber Identity Module (SIM) comprising:
a SIM;
a plastic support on which the SIM is attached, said plastic support comprising a full-sized card defining a frame body, the SIM is attached to and arranged within a portion of the frame body of said plastic support; and
a discontinuity channel between the plastic support and the SIM, and around the SIM, said discontinuity channel being interrupted by only first and second connecting portions each having a triangular shape;
the SIM comprising
the first connecting portion being at a first side of the SIM, attaching the SIM to the frame body;
the second connecting portion being at a second side of the SIM, attaching the SIM to the frame body, the second side being adjacent to the first side,
a lateral recess formed on each side of each connecting portion and extending no longer than an edge of a base of each connecting portion to let the plastic support be broken between the breaking point and the opposing breaking point without precut lines when the SIM is detached, a minimum size of each lateral recess makes the long side and the short side of the SIM planar and protects undesirable substances to be filled in each lateral recess;

the discontinuity channel comprising
a first hole surrounding a first portion of the SIM arranged between the first connecting portion and the second connecting portion, and
a second hole surrounding a second portion of the SIM arranged between the first connecting portion and the second connecting portion.

5. The SIM module according to claim 4 , wherein said first side is shorter than said second side, and said first connecting portion is disposed approximately at a center of said first side.

6. The SIM module according to claim 5 , wherein said second connecting portion is arranged at said second side at a farther position from said first side than a center of said second side.

7. A method for manufacturing a SIM module, comprising:
embedding a SIM in a plastic support; and
forming a discontinuity channel between the plastic support and the SIM, and around the SIM, while leaving first and second triangular shaped attachment points of the plastic support, which interrupt the discontinuity channel and attach the SIM to the plastic support, and a lateral recess formed on each side of each attachment point and extending no longer than a width of a base of each attachment point and extending no longer than an edge of a base of each attachment point to let the plastic support be broken between the breaking point and the opposing breaking point without precut lines, a minimum size of each lateral recess makes a long side and a short side of the SIM planar and protects undesirable substances to be filled in each lateral recess, the first triangular shaped attachment point being at the short side and the second triangular shaped attachment point being at the long side of the SIM.

8. The method according to claim 7 , wherein a depth of each lateral recess in the SIM decreases proportionally to a distance from each triangular shaped attachment point.

9. The method according to claim 7 , wherein said discontinuity channel has a width between 1/7 and 1/15 of said short side of the SIM.
