Deleted an SMS? Don't hope to retrieve it

[Ccssgm]

IF YOU have deleted an important text message, don't expect your cellphone company to have a magical backup server that will bail you out.

One Singapore man recently found that out the hard way when he tried to recover messages that he had trashed nine months ago.

 

Mr Huang Yongliang wrote to The Straits Times Forum this week asking about the possibility of retrieving the long-since-deleted texts.

 

'I got curious about the policies on retrieving SMSes when I accidentally deleted mine,' said Mr Huang.

 

The 27-year-old said he wanted the texts for 'personal reasons', but declined to elaborate.

 

Telecom companies, though, said customers can practically kiss the messages goodbye once they hit the delete button. The companies handle billions of messages annually and deleted SMSes are expunged from servers almost immediately, they say.

 

SingTel, for example, said it processes 20 million text messages a day. That adds up to around seven billion a year.

 

'It is therefore not economically or physically viable to store SMSes in our system for retrieval purposes,' said its corporate communications manager Cheam Tze Hui in a statement.

 

There are a few exceptions. Logs that record the phone number, date and time of an SMS are captured and stored. StarHub and M1 keep these records for seven years and one year respectively. It is understood that these logs serve as verification when customers dispute SMS charges on their bills.

 

Meanwhile, telecom companies say they also face privacy concerns when it comes to releasing text messages. Even if they are still on a backup server, SingTel said it will not release them - not even to someone who wants to retrieve his own message.

 

Telecom companies will, however, release the information to the police and the courts. The former have the right to such information when they are investigating a crime.

 

In 2001, police probing fake bomb threats sent via SMS traced the texts to a 20-year-old national serviceman. They tracked him using help from the telcos, which would not specifically reveal the method. But the telcos suggested that it involved SMS logs.

 

In civil lawsuits, a judge can order companies to release messages if they are relevant to the case, according to Mr P. Padman, a partner in law firm Tito Isaac & Co. He has encountered this in defamation and divorce cases in the past. However, telcos are obliged to give the courts only information which they still possess.

 

The only way to be certain of retaining the SMSes for one's own use is to keep them in phones, according to service providers.

 

Two telcos - M1 and StarHub - said SMSes are purged from their systems as soon as they are delivered. SingTel would only say that while this is not done daily, it is fairly regular.

 

If We Pay for the Service,Can the SMS retrieve Back ?

look at the huge volume of SMS sinktel processes from incoming and outgoing SMS.

 

consider the math.

 

one standard SMS can hold up to 160 english characters. (for chinese characters it maybe 2-byte per character). if one character is 1 byte, the telco needs 160bytes of storage space. multiply by the 20mil sms you get 3.2Gbyte storage per day. 96Gbyte per month. 1.15Tbyte per year.

 

are the telcos willing to keep so much sms?

Frankly .... 1.15TB/yr is nothing.

 

Go calculate the backup that Gmail has to do ....

why the sudden need of retrieving an SMS that he trashed 9 months ago? and when not able to do so, why blame the telcos for not being to retrieve.

 

They ain't the one who presses the DEL button.. moreover, is 9 months ago......

[Weixiang_2008]

if its just a few days or weeks ago, can still undertstand.. 9 months?

 

[Picantorian]

ya lor.. 9 months.. i also say..

 

wonder why would forum even post this letter out.. he sounded like the telcos have to responsible to backup his stuff for him..

[Gadgeter]

are we expecting to see more of such from the new gen??

 

If the Telcos had kept the sms for 9months, scali he turn around and sue the Telcos for invation of privacy?

1.5Tbyte is no big deal..... I've seen 15TB filesystems. There are storage systems that can hold petabytes worth of digital data.

[User12343]

correct. no big deal, but at whose cost?

[Picantorian]

well.. we always have a reason for every logic we want to believe.

bro. Gmail T&C also never guarantee you backups leh. If you hit delete, and ask gmail to restore 1 minute later, they will also tell you go fly kite.
