The sketch is a bit too big and contains parts which are not related to GSM. Should I show the complete sketch? BTW the library I used is the default GSM library which is present in the IDE.HDatta– HDatta2016-01-29 15:22:18 +00:00Commented Jan 29, 2016 at 15:22

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. arduino-uno), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
