There is no one single product/program that recovers logical and physical data from all mobile 'phones. Each model/make is different, so you may need to resolve that issue first.

How can you "see" deleted SMS messages?

It really depends on the phone. If it is a CDMA phone (not likely where you are) or a GMS phone. GSM phones store some of the SMS messages on the SIM card. Try using SIMcon. But it really does depend on the phone whether you can recover the deleted SMS messages.

Unfortunately Oxygen forensic will not recover deleted information from the mobile phone. Like BraneRift said SIMcon can be used to recover deleted text from the SIM card, but there is currently no well known software for recovering deleted information from handset memories. In the last year a lot of work has been done in the industry in dumping the memory (fondly refered to as hex dumps) of handsets and searching for coded text messages in these binary files. There are people working on software for doing this, but as previously mentioned every handset stores its data differently and therefore this work is insanely time consuming and i don't know of a commercial package available yet
Obviously there are many forensic tools for recovering standard data from phones, such as .XRY, Mobiledit forensic, Phonebase2, Oxygen forensic and Paraben now own SIMcon!

The last three phones I've owned have all been GSM, and not one has stored SMS messages on the SIM card unless you explicitly told it to copy them to the card (usually as part of migration from one phone to another.)

That is interesting for every text to be stored on the handset based on three different GSM handsets, for it overrides, in a way, the requirement for SMS class of message. Also, SCM type message implies text prepared on handset and not SIM orientated.

SIMs & USIMs are changing where more and more data will be stored on these devices. USIM-Detective for example acquires stored and deleted data from particular GSM cards and USIM that it would appear other readers don't. So having a range of tools is always recommended.

We can recover deleted data from handsets where it is necessary for a case. The procedures for extraction and harvesting (given the variety of makes/models on the market) can be labour intensive though.

This is why I was interested in cfprof response to the original poster in this thread

How can you "see" deleted SMS messages?

I note the original poster has not come back to respond.

To me, the only way to "see" them is to use forensics software. But then why ask what software to use??????

Confusing…..

Have anyone considered a subpoena of the carrier to provide the data?

I am unconvinced carriers do not have at least a 'short period' storage of SMS messages.

I say this because some phones cannot accept, for example, MMS messages. To fix that problem carriers send a standard SMS to the non-compatible system and store the MMS, accessible online by the recipient.
