Free SMS service like text4free
Websites that providing free SMS service have several modes: websites such as txtbe make money by the click of advertising from visitors. But txtbe was not reachable in past few days, it makes me doubt whether this mode is feasible; then it is the mode of Betamax “free” sms service, which requires customers buy credit first, then you can enjoy the “free” service; the third kind of mode is what will be discussed in this post, which provides free sms service without cost at all…
I guess a lot of people know the GizmoCall free VoIP service and the Gizmo Project “Skype Killer” VoIP products from the same company. But there are fewer people know the GizmoSMS free sms service from this company. One reason is that free sms service is not as attractive as free VoIP call. On the other hand, this service is not so reliable. The real reason is that this “free” service depends on the exsiting “email to sms gateway” service from the mobile operator. The secrect is most (or all) mobile operators have email2sms gateways. So if users send emails to these gateways, corresponding mobile numbers will receive SMS. For example, customers from T-Mobile Netherlands can receive SMS via email addresses of +31(mobile number starting with 6)@gin.nl. While some mobile operator keep their SMS gateways as business secrects, there are also many mobile operators provide these SMS gateways as public service to customers. You can find many lists of SMS gateways on the internet。It seems that Google Maps provides sending address information to mobile phones via SMS also replies on this kind of service.
Many websites including text4free make a dedicated page to enable visitors send free SMS via this web interface without effort to find SMS gateways by themselves. text4free also provide code that you can embed into your own website as below. But there are several problem of this kind of service: First, some mobile operators require receivers to enable the email to sms service by themselves and some operator will charge receivers; Second, many users cannot send free SMS successfully because of incorrect mobile number formati. All these need users try by themselves. But as long as it is free, there is no reason to complain.
