| As cspeeks said, one of the most common problems is de SIM reader, a trick that is useful sometimes is to clean the pines where the SIM card is inserted, clean the SIM it self, and other more "risky" is to push the card to the reader.You may want to try putting a small sheet of paper (a post-it woudn't be a good idea because the glue, but a normal sheet of the same size would be ok), fold the paper to the SIM size, put the paper in the back of the SIM, usually under the battery. |
