Help with text settings

Hi guys.. can someone help me with wat im facing..
When ever im texting some one on snap chat.. typing more than 3 digits are sent as a call number.. dots are automatically taken as website link.. like if iam typing 100 and sending it.. it comes as call 100.. if iam sending 1000 it comes as call 1000.. if iam writing time as well till 9.59 it shows correctly.. 10.10 again it sends as call 10.10. Im tired of searching the internet. May be im not using correct terms... also its happening in snapchat only. Rest apps like whatsapp and all are fine. Pls help its irritating.
Thanx in advance
