TPG shifts from Optus to Vodafone: How do its new mobile plans compare?

TPG's month-to-month offering is switching networks.
After signing an alliance deal with Vodafone, TPG is migrating its mobile customers from Optus' 4G network to the Vodafone 4G network. It has also revamped its plans. Here's what it will now offer on its month-to-month no-contract deals:
Plan | Cost/month | Data | Calls | Text |
---|---|---|---|---|
T4G I | $19.99 | 1.3GB | From $400 included value | From $400 included value |
T4G II | $29.99 | 2GB | Unlimited | Unlimited |
T4G III | $39.99 | 5GB | Unlimited | Unlimited |
On the $19.99 plan, a 2-minute call costs $2.38 and texts are 25.3 cents. There's a $10 SIM charge for new customers. Excess data is charged at $10 for a 1GB block.
Those plans are slightly more generous than TPG's previous Optus-only offerings. Under the old deals, the $35 XL plan had 2GB of data, while the $45 XXL had 6GB.
Incidentally, the shift makes TPG the first mobile virtual network operator (MVNO) in Australia to offer access to Vodafone's 4G network (other than Vodafone itself). Every other MVNO that runs on Vodafone's network (a list that includes Lebara, CMobile and GoTalk) only uses the 3G network.
